You can put this solution on YOUR website!
Solving for y for the first equation we get \"y=expr%285%2F4%29x%2Bexpr%285%2F4%29\" and for the 2nd equation \"y=expr%281%2F2%29x%2Bexpr%287%2F2%29\". Looking at the graph below you'll see the solution appears to be (3,5). That means if you substitute 3 for x in both equations, you should get y=5 both times... and we do!
