Help me please

Which equation is equivalent to 5 (x - 1) + 4x = 13 - 2x

A. 7x = 18

B. 7x = 14

C. 11x = 18

D. 11x = 8

Answer 1

C.
After distributing 5 to the parenthesis you get 5x-5+4x=13-2x. Combine like terms and you get 9x-5=13-2x. Add 2x to both sides and get 11x-5=13 then add 5 to both sides. You get 11x=18.

Answer 2

5(x-1)+4x=13-2x
5x-5+4x=13-2x
9x-5=13-2x
11x-5=13
11x=18
x=18/11
