In order to solve an equation in two variables, you need a second related equation with the same two variables. This is called a linear system. When graphed, they either intersect with one solution for (x, y), they don't intersect at all (parallel) and have no solution in (x, y), or they graph the same line. So find that other equation, and we'll talk.
