We are given:
\(\displaystyle{2}{\left({y}-{4}\right)}\leftarrow{18}\)
Divide both sides by 2:
\(\displaystyle{\frac{{{2}{\left({y}-{4}\right)}}}{{{2}}}}\leftarrow{\frac{{{18}}}{{{2}}}}\)
\(\displaystyle{y}-{4}\leftarrow{9}\)
Add 4 to both sises:
\(\displaystyle{y}-{4}+{4}\leftarrow{9}+{4}\)
\(\displaystyle{y}\leftarrow{5}\)
