Answer 3

Sure, I'll solve each equation for you:

1. 5(x-1) - 4(x-2) = 10

To solve this equation, first distribute the numbers inside the parentheses: 5x - 5 - 4x + 8 = 10

Next, combine like terms: (5x - 4x) + (8 - 5) = 10 x + 3 = 10

Now, isolate the variable by subtracting 3 from both sides: x = 10 - 3 x = 7

2. 3(x-4) = 9

Distribute the number inside the parentheses: 3x - 12 = 9

Add 12 to both sides to isolate the variable: 3x = 9 + 12 3x = 21

Finally, divide both sides by 3 to solve for x: x = 21 / 3 x = 7

3. (2x + 3) + (5x + 4) = 7

Combine like terms: 2x + 5x + 3 + 4 = 7

Add the numbers together: 7x + 7 = 7

Now, isolate the variable by subtracting 7 from both sides: 7x = 7 - 7 7x = 0

To find x, divide both sides by 7: x = 0 / 7 x = 0

4. 2x - 6 = 2

Add 6 to both sides: 2x = 2 + 6 2x = 8

To find x, divide both sides by 2: x = 8 / 2 x = 4

So, the solutions to the equations are:

1. x = 7
2. x = 7
3. x = 0
4. x = 4
