Question

What value of x makes this statement true?
3x + 4 = 9x -8​

A. -2
B. 1
C. 2
D. 12

Answer 1

Answer:

C. 2

Step-by-step explanation:

3x + 4 = 9x - 8​  (subtract 4 from both sides)

3x = 9x - 8​ - 4

3x = 9x - 12   (subtract 9x from both sides)

3x - 9x = -12

-6x = -12   (divide both sides by -6)

x = -12 / (-6)

x = 2
