Question

a) 3 (x + 6) = 2 ( x - 5)


b) 9 (x - 1) = 6 (x + 3)


c) 8 (x - 2) = 12 (x - 3)

Answer 1

a) 3 (x + 6) = 2 ( x - 5)

3x + 18 = 2x - 10

3x - 2x = -10 - 18

x = - 28

b) 9 (x - 1) = 6 (x + 3)

9x - 9 = 6x + 18

9x - 6x = 18 + 9

3x = 27

x = 9

c) 8 (x - 2) = 12 (x - 3)

8x - 16 = 12x - 36

36 - 16 = 12x - 8x

20 = 4x

x = 5
