Привет! Вот ответ на твой вопрос.

Answer 2

Let's solve each of these equations step by step:

1. 4(x + 5) = 5(x + 4) - x

First, distribute the numbers on the left and right side of the equation:

4x + 20 = 5x + 20 - x

Now, combine like terms:

4x + 20 = 4x + 20

Notice that the variable terms on both sides of the equation cancel each other out. This means that the equation has infinitely many solutions, as the variable cancels out, and it simplifies to:

20 = 20

Since this equation is always true, any value of x will satisfy it. So, there are infinitely many solutions for this equation, and you can't find a single unique value of x.

2. 6x + 3 = 6(x + 5)

First, distribute the 6 on the right side of the equation:

6x + 3 = 6x + 30

Now, subtract 6x from both sides to isolate the constant term:

3 = 30

This equation is not true because 3 is not equal to 30. Therefore, there is no solution to this equation.

3. 8x + 4 = 2x + 22

First, subtract 2x from both sides of the equation:

8x - 2x + 4 = 22

Now, combine like terms:

6x + 4 = 22

Next, subtract 4 from both sides of the equation:

6x = 18

Finally, divide both sides by 6 to isolate x:

6x/6 = 18/6 x = 3

So, the solution to this equation is x = 3.

4. -12n - 3 = 1ln - 3

It seems there might be a typo in the equation. I assume you meant:

-12n - 3 = 1n - 3

First, add 3 to both sides of the equation:

-12n - 3 + 3 = 1n - 3 + 3

-12n = 1n

Now, add 12n to both sides to isolate n:

-12n + 12n = 1n + 12n

0 = 13n

Since 0 cannot equal 13n unless n is equal to 0, the solution to this equation is:

n = 0

So, for equation 4, n = 0 is the solution.
