Aura thinks the solution to the systems of equations below is (−2, 4) while Edison thinks the solution is (2, −2). Teresito thinks they are both wrong. Who is correct? Justify your answer. Homework Help ✎

3x + 2y = 2
5x − 12 = y

Use substitution to solve the system.

3x + 2(5x + 12) = 2

Solve for x.

Use your solution for x to solve for y.

Substitute the points into both equations to check your solutions.
