Once again, we graph the 2 lines and the intersection point gives the solution for the simultaneous equations.

2x − 3y = -6 has x-intercept -3, and y-intercept 2.

x + y = 7 has x-intercept 7 and has y-intercept 7.

The graph is as follows:

So the solution for the system (from the graph) is (3, 4).
