There is one set of solutions.
Explanation:
Both equations are linear, so there is either one set of solutions, no solutions, or infinite solutions.
In order to graph the system, you can rewrite both equations to a formula form (
The graph of the system is equivalent to the graph of both linear formulas:
The lines have one point of intersection, so the system has one set of solutions.
