7. x = 0

8. x = 9

9. x = -4

10. x = 7

Explanation:

1.

• 
  `-10x = -8x + 12`

• 
  `-10x+8x=-8x+12+8x`
• 
  `-2x=12`

• 
  `-2x/-2=12/-2`
• 
  `x=-6`

2.

• 
  `9-5x+x=1-x+x`
• 
  `-4x+9=1`

• 
  `-4x+9-9=1-9`
• 
  `-4x=-8`

• 
  `-4x/-4=-8/-4`
• 
  `x=2`

3.

• 
  `-2x+16-x=x-2-x`
• 
  `-3x+16=-2`

• 
  `-3x+16-16=-2-16`
• 
  `-3x=-18`

• 
  `-3x/3=-18/-3`
• 
  `x = 6`

4.

• 
  `(-4)(6x)+(-4)(-2)= -8x-40`
• 
  `-24x+8=-8x-40`

• 
  `-24x+8+8x=-8x-40`
• 
  `-16x+8=-40`

• 
  `-16x+8-8=-40-8`
• 
  `-16x=-48`
• 
  `-16x/-16=-48/-16`
• 
  `x=3`

5.

• 
  `37 - 8x = (-7)(x)+(-7)(-6)`
• 
  `-8x+37=-7x+42`
• 
  `-8x + 37 + 7x = -7x + 42 + 7x`
• 
  `-x+37=42`
• 
  `-x+37-37=42-37`
• 
  `-x=5`
• 
  `-x/-1=5/-1`
• 
  `x=-5`

6.

• 
  `6x+(-2)(2)+(-2)(8x) = 10 + 4x`
• 
  `6x-4-16x = 10 + 4x`
• 
  `-10x - 4 = 4x + 10`
• 
  `-10x - 4 -4x=4x+10-4x`
• 
  `-14x-4=10`
• 
  `-14x-4+4=10+4`
• 
  `-14x=14`
• 
  `-14x/-14=14/-14`
• 
  `x=-1`

7.

• 
  `(-2)(x) + (-2)(1) = (2)(x) + (2)(-1)`
• 
  `-2x-2=2x-2`
• 
  `-2x-2-2x = 2x - 2 - 2x`
• 
  `-4x - 2 = -2`
• 
  `-4x-2+2=-2+2`
• 
  `-4x=0`
• 
  `-4x/-4=0/-4`
• 
  `x=0`

8.

• 
  `(-3)(x)+(-3)(3)=(-6)(x)+(-6)(-3)`
• 
  `-3x-9=-6x+18`
• 
  `-3x-9+6x=-6x+18+6x`
• 
  `3x-9=18`
• 
  `3x-9+9=18+9`
• 
  `3x=27`
• 
  `3x/3 = 27/3`
• 
  `x=9`

9.

• 
  `6x-36=(-4)(-2x)+(-4)(7)`
• 
  `6x-36= 8x -28`
• 
  `6x-36-8x = 8x - 28 - 8x`
• 
  `-2x-36=-28`
• 
  `-2x-36+36=-28+36`
• 
  `-2x = 8`
• 
  `-2x/-2=8/-2`
• 
  `x=-4`

10.

• 
  `(2)(x)+(2)(1) = -2x + 30`
• 
  `2x+2=-2x+30`
• 
  `2x+2+2x=-2x+30+2x`
• 
  `4x+2=30`
• 
  `4x+2-2=30-2`
• 
  `4x=28`
• 
  `4x/4=28/4`
• 
  `x=7`
