1) 7x - 3 (x-4) = 8 2) 4x-8+2x=40 3) 6x - 6+11=53 4) 17=x-3x-3

1.) 7x - 3 (x - 4) = 8 Multiply/distribute 3 into (x - 4)

7x - 3x + 12 = 8

4x + 12 = 8 Subtract 12 on both sides

4x = - 4 Divide 4 on both sides

x = - 1

2.) 4x - 8 + 2x = 40

6x - 8 = 40 Add 8 on both sides

6x = 48 Divide 6 on both sides

x = 8

3.) 6x - 6 + 11 = 53

6x + 5 = 53 Subtract 5 on both sides

6x = 48 Divide 6 on both sides

x = 8

4.) 17 = x - 3x - 3

17 = - 2x - 3 Add 3 on both sides

20 = - 2x Divide - 2 on both sides

-10 = x
