Question

12(2x - 8) = 4(5 - 2x) + 3(7 - 3x)

Answer 1

distribute all of the numbers in front of the parenthesis

Answer 2

combine like terms

Answer 3

apply distribution first
24x - 96 = 20 - 8x + 21 - 9x
then combine coefficients of x on the left, and constants on the right
41x = 137
divide by 41 on both sides
x = 137/41
