Homework Help: Algebra

Posted by Cassie on Friday, February 27, 2009 at 6:01pm.

Solve the system of equations using substitution.

x + 4y = -5
3x - 8y = 45

When I tried to solve it, I got x=-17 and y=-3. When I plugged these into the first equation, it didn't work out at all. Could someone please show me the steps so I can see where I went wrong? Thank you!
