Solve the system of equations:

\[
-3x + 7y = -12
\]

\[
3x + 8y = 12
\]

line up both equations according to terms and add -3x + 7y= -12 + 3x + 8y=12
15y= 0 y= 0 so plug back that into either equations and get x=4

The solution to the system of equations is (x, y) = (4, 0). This was found by eliminating one variable and substituting back to solve for the other variable. This method shows that the lines represented by these equations intersect at the point (4, 0).
