Answer:


\begin{gathered} y=(9)/(6)x-9 \\ l=(P)/(2)-w \end{gathered}

Explanation:

To solve the following equations, we need to isolate the variable asked using inverse operations to solve equations.

Remember that addition and subtraction are inverse operations, as multiplication and division.

Therefore,


\begin{gathered} a\text{. Solve for y} \\ 6y=9x-54 \\ y=(9)/(6)x-(54)/(6) \\ y=(9)/(6)x-9 \end{gathered}
\begin{gathered} b\text{. Solve for l} \\ P=2l+2w \\ 2l=P-2w \\ l=(P)/(2)-(2)/(2)w \\ l=(P)/(2)-w \end{gathered}
