Solution

We want to solve


\begin{gathered} 15(y-4)-2(y-9)+5(y+6)=0 \\ Exapnd\text{ the brackets } \\ 15y-60-2y+18+5y+30=0 \\ 15y-2y+5y-60+18+30=0 \\ 18y-12=0 \\ 18y=12 \\ \text{Divide both sides by 18} \\ (18y)/(18)=(12)/(18) \\ y=(12)/(18) \\ y=(2)/(3) \\ \\ \text{The answer is y = }(2)/(3) \end{gathered}
