Answer 2

It seems like you've provided a list of equations. It looks like you want to solve these equations for the variable 'x'. I can help you with that. Let's solve each equation step by step:

Equation 1: 3(2x-2) - 5x + 4 = -20

Distribute the 3: 6x - 6 - 5x + 4 = -20

Combine like terms: 6x - 5x - 6 + 4 = -20 x - 2 = -20

Add 2 to both sides: x = -20 + 2 x = -18

Equation 2: -8x - 3(4 - 3x) + 8 = -40

Distribute the -3: -8x - 12 + 9x + 8 = -40

Combine like terms: -8x + 9x - 12 + 8 = -40 x - 4 = -40

Add 4 to both sides: x = -40 + 4 x = -36

Equation 3: 6x - 2(3 - x) - 9x - 5 = -8

Distribute the -2: 6x - 6 + 2x - 9x - 5 = -8

Combine like terms: 6x + 2x - 9x - 6 - 5 = -8 -x - 11 = -8

Add 11 to both sides: -x = -8 + 11 -x = 3

Multiply by -1 to solve for x: x = -3

Equation 4: 9(3 - 2x) - 6(4 - 3x) - x = -7

Distribute the 9 and the -6: 27 - 18x - 24 + 18x - x = -7

Combine like terms: 27 - 24 - x = -7 3 - x = -7

Add x to both sides: 3 - x + x = -7 + x 3 = -7 + x

Subtract 7 from both sides: 3 - 7 = x x = -4

Equation 5: -6(2 - 3x) - 7(2x + 2) - 5x = -8

Distribute the -6 and the -7: -12 + 18x - 14x - 14 - 5x = -8

Combine like terms: 18x - 14x - 5x - 12 - 14 = -8 -1x - 26 = -8

Add 26 to both sides: -1x = -8 + 26 -1x = 18

Multiply by -1 to solve for x: x = -18

So, the solutions for the given equations are:

1. x = -18
2. x = -36
3. x = -3
4. x = -4
5. x = -18
