Question

Simplify and solve the following linear equations.15 (Y - 4 - 2) Y - 9 + 5 (Y + 6)=0

Answer 1

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}`
