A)3x + 5 = 5x - 13

3x - 5x = - 13 - 5 - 2x = - 18

x = - 18 / - 2

x = 2

B)5(7 - x) = 31 - x

35 - 5x = 31 - x - 5x + x = 31 - 35 - 4x = - 4

x = - 4 / - 4

x = 1

C)4(2 - 3x) = - 2x - 27

8 - 12x = - 2x - 27 - 12x + 2x = - 27 - 8 - 10x = - 35

x = - 35 / - 10

x = - 7 / - 2

D)6x - 8 = 4( - 2 + 5)

6x - 8 = - 8 + 20

6x = - 8 + 20 + 8

6x = 20

x = 20 / 6

E)3(2x - 2) = 2(3x + 9)

6x - 6 = 6x + 18.
