Question

-7(2x+2)-15=4(x-5)+12

Answer 1

-7(2x+2)-15=4(x-5)+12-14x -14 - 15 = 4x -20 + 12
-14x -4x = +14 + 15 - 20 + 12
-18x = 41 - 20
-18x = 21 [-1]
18x = - 21
x = -21/18

Answer 2

-7 ( 2x + 2) - 15 = 4( x - 5 ) + 12
-14x - 14 - 15 = 4x - 20 +12
-14x - 4x = -20 + 12 +14 + 15
- 18 x = -8 + 14 + 15
- 18x= +6 + 15
-18x = 21 ( - 1)
18x=- 21
x= $\frac{-21}{18}$ x= $\frac{-7}{6}$
