Question

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

Answer 1

Solution

We want to solve

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