    I know that there is a way to solve this using the equations, but it's been years (at least 5) since I was last in an algebra class. So how I would solve this would be to make the two lines on a graph, and the answer is where the two lines meet on the graph.

    another way to solve is to set the y values equal and solve the one equation with one variable . Use this value in either of the original expressions to get the value of y
