How may we be of help to you, with this exercise? I mean, what have you considered so far? Where are you stuck?

Have you seen any lessons on solving a system of two equations with two variables?

(There are more than four methods to solve this exercise. I don't know what your class is teaching. You need to give us a clue.)
