We are given the following equation:


-4x-y=24

We are told that that part of the solution is:


(x,y)=(-,8)

Since we are given the value of "y", we can replace this value in the given equation:


-4x-8=24

Now we solve for "x", first by adding 8 on both sides:


\begin{gathered} -4x-8+8=24-8 \\ -4x=16 \end{gathered}

Now we divide both sides by -4


x=(16)/(-4)=-4

Therefore the complete solution is:


(x,y)=(-4,8)
