Question 55066: Solve the system by graphing, addition and substitution methods. 5x – 4y = –5, x – 2y = –7

Solving for y for the first equation we get and for the 2nd equation . 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!
