If you were to draw both graphs, then the point that they cross will give you the solutions for both x and y at the same time.

To draw the graphs, get them into the form y = mx+c, where m is the gradient and c the y intercept.

We have then y = 2/5x +0 & y = 3/2x+0

Therefore the only solution is x = y = 0
