I 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.
Solve the system of equations by first writing it in matrix form and then using Gauss-Jordan elimination.
x-4y =-5
-2x + 9y = 125
