Because the equation is the difference of two perfect squares, it factors into expr%28y%2F5%29%2Bexpr%28x%2F8%29 and expr%28y%2F5%29-expr%28x%2F8%29. So you have two equations to solve. Solving each for y we get y=-expr%285%2F8%29x%2B5 and y=expr%285%2F8%29x%2B5. The graph is below and the solution is where they intersect, which is (0,5).
