Answer: (7.2, -3.2)

Explanation:

First, we will graph these equations. See attached. One has a y-intercept of -5 and then moves four units right for every unit up (we get this from the slope of 1/4). The other has a y-intercept of 4, and moves right one unit for every unit down (we get this from the slope of -1).

The point of intersection is the solution, this is the point at which both graphed lines cross each other. Our solution is:

(7.2, -3.2) x = 7.2, y = -3.2
