ANSWER:


(2,3)

Explanation:

We have the following system of equations:


\begin{gathered} y=5x-7 \\ -3x-2y=-12 \end{gathered}

Solving by Substitution


\begin{gathered} -3x-2\cdot(5x-7)=-12 \\ -3x-10x+14=-12 \\ -13x=-12-14 \\ x=(-26)/(-13) \\ x=2 \end{gathered}

Now, for y, replacing:


y=5\cdot2-7=10-7=3

The solution is:


(2,3)
