Question

27 = 3x – 3(6 – 2x) what does x equal?

Answer 1

`27=3x-3(6-2x)`

distribute the 3 in the parentheses

`27=3x-18+6x`

simplify common factors

`27=9x-18`

add 18 on both sides and simplify

`\begin{gathered} 27+18=9x-18+18 \\ 45=9x \end{gathered}`

divide by 9 on both sides

`\begin{gathered} (45)/(9)=x \\ 5=x \end{gathered}`
