Do it by the addition method. Eliminateby multiplying the first equation through by 5 and the second equation through by 2. Substitute ±3 for x in So there are 4 solutions: (3,1), (3,-1), (-3,1), and (-3,-1) Here is the graphical solution: The black oval curve is the graph of the first equation. The red curve (in two parts) is the graph of the second equation Notice that they intersect at those 4 solution points. Edwin
