Answer 2

1. Solving for x: -4x + 10 = 5x + 2 -4x - 5x = 2 - 10 -9x = -8 x = 8/9

2. Solving for x: -7x - 20 = 6x + 70 -7x - 6x = 70 + 20 -13x = 90 x = -90/13

3. Solving for x: -5x + 15 = 20 - 6x -x = 5 x = -5

4. Solving for x: 2(x + 8) = 30 + 7x 2x + 16 = 30 + 7x 2x - 7x = 30 - 16 -5x = 14 x = -14/5

5. Solving for x: -3x + 8 - x = 4x - 9 -4x + 4x = -9 - 8

• x = -17 x = 17

6. Solving for x: -4x - 8 + x - 2x = 5x - 10 -5x - 8 = 5x - 10 -5x - 5x = -2 x = 2/5

7. Solving for x: 90 - 12x = 45 - 18x 6x = 45 - 90 6x = -45 x = -7.5

8. Solving for x: -100 + 7x = -x + 20 8x = 120 x = 15

9. The equation -9x + 10 is not an equation since it does not have an equal sign, so it cannot be solved for x.

I hope this helps!
