Question

Solve this following system by graphing
X-y=4
X+y=2

Answer 1

The answer is x = 3 and y = -1

Explanation:

If you were to graph the two lines, their equations would be y = x - 4 and y = -x + 2. The two lines intersect at the point (3, -1), so the solution to the system is x = 3 and y = -1.
