4(-2y) =700     simplify

-8y = 700        divide both sides by -8

y = -87.5   

Just as happy7 found.......!!!

$${\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{\,-\,}}\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{y}}\right) = {\mathtt{700}} \Rightarrow {\mathtt{y}} = {\mathtt{\,-\,}}{\frac{{\mathtt{175}}}{{\mathtt{2}}}} \Rightarrow {\mathtt{y}} = -{\mathtt{87.5}}$$

Here!
