Question

Solve 2(x + 7) - 4 = 24

Answer 1

`x=7`

1) In this expression, we'll need to distribute factor 2 over the terms within the parentheses.

2) So, let's distribute that (also known by the acronym FOIL).

`\begin{gathered} 2(x+7)-4=24 \\ 2x+14-4=24 \\ 2x+10=24 \\ 2x=24-10 \\ 2x=14 \\ (2x)/(2)=(14)/(2) \\ x=7 \end{gathered}`

3) Thus the answer is x=7
