Answer 1

4x - 8 = -4(2x - 3) + 4

4x - 8 = -8x + 12 + 4

4x - 8 = -8x + 16

4x = -8x + 16 + 8

4x = -8x + 24

4x + 8x = 24

12x = 24

x = 24/12

x = 2

3(5x + 9) = 2(2x + 3)

15x + 27 = 4x + 6

15x = 4x + 6 - 27

15x = 4x - 21

15x - 4x = -21

11x = -21

x = -21/11

x/3 + 1 = 5

x/3 = 5 - 1

x/3 = 4

x/3 · 3 = 4 · 3

x = 12
