Question

Solve –4(6x + 3) = –12(x + 10).



A. x = 2
B. x = 9
C. x = –5
D. x = 5

Answer 1

Answer:

B

Step-by-step explanation:

distribute parenthesis on both sides of the equation

- 24x - 12 = - 12x - 120 ( add 12x to both sides )

- 12x - 12 = - 120 ( add 12 to both sides )

- 12x = - 108 ( divide both sides by - 12 )

x = 9 → B
