The point (2, 1) is a solution to which of the following systems of equations? 2x + y = 5 and −2x + y = 2
−2x − y = −5 and 2x − y = 2
−x + y = 3 and −3x + y = −5
x + y = 3 and 3x − y = 5

We can solve this problem by testing the solution against each system of equations. We'll do this by substituting the point into each equation for each system.

Since both equations in the final system are true when solved with , the answer is the last system.
