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
There are two ways to find out who is correct.
You can graph the system of equations and find the point of intersection,
or you can substitute the values for x and y that each person got into both equations.
Edison was correct. Be sure you can explain why.
