x-4y =-5

-2x + 9y = 125

**PsyDAG**, Thursday, January 31, 2013 at 5:35pmI don't know if I am using the same form or "Gauss-Jordan" elimination.

2x - 8y = -10

-2x + 9y = 125

Add the two equations.

y = 115

Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
