Answer:
Solution: (2, 2)
Step-by-step explanation:
The first equation describes a line with a y-intercept of 3 and a (downward) slope of -1/2. That is, it has a "rise" of -1 for a "run" of 2.
__
The second equation describes a line with a y-intercept of -2 and an (upward) slope of 2. That is, it has a "rise" of 2 for a "run" of 1.
These two lines meet at the point (2, 2), which is the solution to the set of equation. Those are the values of x and y that satisfy both equations.
