Question

Solve for x.

8(x + 1) - 3(x + 4) = 7(2 - x)

Answer 1

8(x+1) = 8x + 8
-3(x + 4) = -3x - 12
7(2 - x) = 14 - 7x

8x + 8 - 3x - 12 = 14 - 7x

5x - 4 = 14 - 7x

Add 7x to both sides

8x + 7x - 4 = 14 - 7x + 7x

15x - 4 = 14

add 4 to both sides

15x - 4 + 4 = 14 + 4

15x = 18

divide both sides by 15

15x/15 = 18/15

x = 18/15 = 6*3/3*5 = 6/5
