Question
Algebra foundations
$$\displaystyle{2}{\left({y}−{4}\right)}\leftarrow{18}$$

2020-12-06
We are given:
$$\displaystyle{2}{\left({y}-{4}\right)}\leftarrow{18}$$
Divide both sides by 2:
$$\displaystyle{\frac{{{2}{\left({y}-{4}\right)}}}{{{2}}}}\leftarrow{\frac{{{18}}}{{{2}}}}$$
$$\displaystyle{y}-{4}\leftarrow{9}$$
$$\displaystyle{y}-{4}+{4}\leftarrow{9}+{4}$$
$$\displaystyle{y}\leftarrow{5}$$
