1) To solve the equation 2 - 3(x + 2) = 5 - 2x, we can start by simplifying both sides of the equation.
Expanding the left side of the equation, we get:
2 - 3x - 6 = 5 - 2x
Combining like terms, we have:
-3x - 4 = 5 - 2x
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by adding 3x to both sides:
-3x + 3x - 4 = 5 - 2x + 3x
Simplifying further, we have:
-4 = 5 + x
Now, let's isolate the constant term by moving it to the other side of the equation. We can do this by subtracting 5 from both sides:
-4 - 5 = 5 + x - 5
Simplifying, we have:
-9 = x
So the solution to the equation is x = -9.
2) To solve the equation 3 - 5(x + 1) = 6 - 4x, we can start by simplifying both sides of the equation.
Expanding the left side of the equation, we get:
3 - 5x - 5 = 6 - 4x
Combining like terms, we have:
-5x - 2 = 6 - 4x
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by adding 5x to both sides:
-5x + 5x - 2 = 6 - 4x + 5x
Simplifying further, we have:
-2 = 6 + x
Now, let's isolate the constant term by moving it to the other side of the equation. We can do this by subtracting 6 from both sides:
-2 - 6 = 6 + x - 6
Simplifying, we have:
-8 = x
So the solution to the equation is x = -8.
3) To solve the equation 0.2 - 2(x + 1) = 0.4x, we can start by simplifying both sides of the equation.
Expanding the left side of the equation, we get:
0.2 - 2x - 2 = 0.4x
Combining like terms, we have:
-2x - 1.8 = 0.4x
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by adding 2x to both sides:
-2x + 2x - 1.8 = 0.4x + 2x
Simplifying further, we have:
-1.8 = 2.4x
Now, let's isolate the x term by dividing both sides of the equation by 2.4:
-1.8 / 2.4 = 2.4x / 2.4
Simplifying, we have:
-0.75 = x
So the solution to the equation is x = -0.75.
4) To solve the equation 0.4x = 0.4 - 2(x + 2), we can start by simplifying both sides of the equation.
Expanding the right side of the equation, we get:
0.4x = 0.4 - 2x - 4
Combining like terms, we have:
0.4x = -3 - 2x
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by adding 2x to both sides:
0.4x + 2x = -3 - 2x + 2x
Simplifying further, we have:
2.4x = -3
Now, let's isolate the x term by dividing both sides of the equation by 2.4:
2.4x / 2.4 = -3 / 2.4
Simplifying, we have:
x = -1.25
So the solution to the equation is x = -1.25.
5) To solve the equation 4x - 5.5 = 5x - 3(2x - 1.5), we can start by simplifying both sides of the equation.
Expanding the right side of the equation, we get:
4x - 5.5 = 5x - 6x + 4.5
Combining like terms, we have:
4x - 5.5 = -x + 4.5
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by adding x to both sides:
4x + x - 5.5 = -x + x + 4.5
Simplifying further, we have:
5x - 5.5 = 4.5
Now, let's isolate the constant term by moving it to the other side of the equation. We can do this by adding 5.5 to both sides:
5x - 5.5 + 5.5 = 4.5 + 5.5
Simplifying, we have:
5x = 10
Now, let's isolate the x term by dividing both sides of the equation by 5:
5x / 5 = 10 / 5
Simplifying, we have:
x = 2
So the solution to the equation is x = 2.
6) To solve the equation 4 - 5(3x + 2.5) = 3x + 9.5, we can start by simplifying both sides of the equation.
Expanding the left side of the equation, we get:
4 - 15x - 12.5 = 3x + 9.5
Combining like terms, we have:
-15x - 8.5 = 3x + 9.5
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by adding 15x to both sides:
-15x + 15x - 8.5 = 3x + 15x + 9.5
Simplifying further, we have:
-8.5 = 18x + 9.5
Now, let's isolate the constant term by moving it to the other side of the equation. We can do this by subtracting 9.5 from both sides:
-8.5 - 9.5 = 18x + 9.5 - 9.5
Simplifying, we have:
-18 = 18x
Now, let's isolate the x term by dividing both sides of the equation by 18:
-18 / 18 = 18x / 18
Simplifying, we have:
-1 = x
So the solution to the equation is x = -1.
7) The equation 5(2 - 1.5x) - 0.5x = 24 can be simplified as follows:
Expanding the left side of the equation, we get:
10 - 7.5x - 0.5x = 24
Combining like terms, we have:
-8x + 10 = 24
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by adding 8x to both sides:
-8x + 8x + 10 = 24 + 8x
Simplifying further, we have:
10 = 24 + 8x
Now, let's isolate the constant term by moving it to the other side of the equation. We can do this by subtracting 24 from both sides:
10 - 24 = 24 + 8x - 24
Simplifying, we have:
-14 = 8x
Now, let's isolate the x term by dividing both sides of the equation by 8:
-14 / 8 = 8x / 8
Simplifying, we have:
-1.75 = x
So the solution to the equation is x = -1.75.
8) The equation 3(0.5x - 4) = 8.5x - 18 can be simplified as follows:
Expanding the left side of the equation, we get:
1.5x - 12 = 8.5x - 18
Next, let's isolate the x term by moving all the x terms to one side of the equation. We can do this by subtracting 1.5x from both sides:
1.5x - 1.5x - 12 = 8.5x - 1.5x - 18
Simplifying further, we have:
-12 = 7x - 18
Now, let's isolate the x term by moving the constant term to the other side of the equation. We can do this by adding 18 to both sides:
-12 + 18 = 7x - 18 + 18
Simplifying, we have:
6 = 7x
Now, let's isolate the x term by dividing both sides of the equation by 7:
6 / 7 = 7x / 7
Simplifying, we have:
x = 6/7
So the solution to the equation
