Question

Which equation has a solution x= -3

A) 2x - 7 = -1
B) 3x + 8 = 1
C) 1/2x + 8 = 10
D) 1/2(2x - 6) = -6

Answer 1

Answer is D

Step by step:

1/2(2x - 6) = -6
-6 -6
1/2 (-12) = -6
-6 = -6

Answer 2

D

Explanation:

1/2 ( 2x - 6) = -6

1/2 = 0.5

0.5(2x-6) = -6

1x-3=-6

1x=-6+3

x=-3/1

x=-3
