Given that:


-4y-7=9

We are told to find 5y - 6

Solving for y


-4y-7=9

Add 7 to both sides


\begin{gathered} -4y-7+7=9+7 \\ -4y+0=16 \\ -4y=16 \end{gathered}

Divide both sides by -4


\begin{gathered} (-4y)/(-4)=(16)/(-4) \\ y=-4 \end{gathered}

Let us now solve for 5y - 6 by substituting y = -4


\begin{gathered} 5y-6 \\ 5(-4)-6 \\ -20-6=-26 \\ \therefore5y-6=-26 \end{gathered}

Hence,


5y-6=-26
