Question

Determine which equation below has a solution of x = 2.

A. X + 9 = 14 - 3x
B. -4x + 3 = 8x - 21
C. 3x - 6 = 2x + 4
D. 18x - 32 = -23x – 6

Answer 1

answer is B

Explanation:

first you subtract 8x from -4x to get -12x. Then you add the rest on -12x+3=-21. Subtract 3 from both sides.

-21-3=-24 -24 divided by -12= 2
