Cesardelgado40 · Answer

32x + 39 = x + 132

32x - x = 132 - 39

31x = 93

x = 93 / 31

x = 3

8x - 2 = 5 (x + 2)

8x - 2 = 5x + 10

8x - 5x = 10 - 2

3x = 8

x = 8 / 3

8x - 4 = 2 (x + 10)

8x - 4 = 2x + 20

8x - 2x = 20 + 4

6x = 24

x = 24 / 6

x = 4

5(x - 3) = 4 (x + 10)

5x - 15 = 4x + 40

5x - 4x = 40 + 15

x = 55

10x - 8 = 20 + 3x

10x - 3x = 20 + 8

7x = 28

x = 28 / 7.
