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:
Graphs of `y = (2x+6)/3` and `y=-x+7`.
So we see there is one solution for the system (from the graph), and it is `(3, 4)`.
