Answer 2

Let's solve each equation step by step:

1. -5(x-1) = -7x - 13

Expanding the left side: -5x + 5 = -7x - 13

Moving the variables to one side and constants to the other side: -5x + 7x = -13 - 5 2x = -18

Dividing both sides by 2: x = -9

2. 18x + 5 = -15x - 61

Adding 15x to both sides and subtracting 5 from both sides: 18x + 15x = -61 - 5 33x = -66

Dividing both sides by 33: x = -2

3. 3(x-2) = -6x - 15

Expanding the left side: 3x - 6 = -6x - 15

Moving the variables to one side and constants to the other side: 3x + 6x = -15 + 6 9x = -9

Dividing both sides by 9: x = -1

4. -11x + 12 = -3x - 12

Adding 3x to both sides and subtracting 12 from both sides: -11x + 3x = -12 - 12 -8x = -24

Dividing both sides by -8: x = 3

5. 4(x-2) = -10x - 36

Expanding the left side: 4x - 8 = -10x - 36

Moving the variables to one side and constants to the other side: 4x + 10x = -36 + 8 14x = -28

Dividing both sides by 14: x = -2

6. (x-2) = 88 - x

Expanding the right side: x - 2 = 88 - x

Adding x to both sides: 2x - 2 = 88

Adding 2 to both sides: 2x = 90

Dividing both sides by 2: x = 45

7. -5(x + 1) = -x - 27

Expanding the left side: -5x - 5 = -x - 27

Moving the variables to one side and constants to the other side: -5x + x = -27 + 5 -4x = -22

Dividing both sides by -4: x = 5.5 or x = -5.5

8. 7x - 18 + 5x = -33x + 27

Combining like terms on the left side: 12x - 18 = -33x + 27

Adding 33x to both sides and adding 18 to both sides: 12x + 33x = 27 + 18 45x = 45

Dividing both sides by 45: x = 1

So the solutions for the given equations are:

1. x = -9
2. x = -2
3. x = -1
4. x = 3
5. x = -2
6. x = 45
7. x = 5.5 or x = -5.5
8. x = 1
