(a)−5
(b)5
(c)9
(d)−9

Answer 1

C.
`9`

Explanation:

`-4(2x -1) = -6(x +2) -2 \\ -8x +4 = -6x -12 -2 \\ -8x +4 = -6x -14 \\ -8x +4 +6x = -6x -14 +6x \\ - 2x +4 = -14 \\ - 2x +4 -4 = -14 -4 \\ -2x = -18 \\ (-2x)/(-2) = (-18)/(-2) \\ x = 9`

Answer 2

c. 9

Explanation:

-8x+4=-6x-12-2

-8x+6x=-12-2-4

-2x=-18

2x=18

x=18/2

x=9
