Question

Explain how to solve the equation 2(4x - 11) + 9 = 19

Answer 1

$2(4x-11)+9=19 \\ \\ 8x-22=19-9 \\\ \\ 8x-22=10 \\ \\ 8x=10+22 \\ \\ 8x=32 \\ \\ \boxed{x=\frac{32}{8}=4}$

Answer 2

2(4x-11)+9=19 -- expand brackets multiply inner by. Outer terms
8x-22+9=19 -- combine like terms
8x-13=19 -- add 13
8x=32 -- divide by 8

x=4
