-1=2x-9
Consider the second equation. Insert the known values of variables into the equation.
2x-9=-1
Swap sides so that all variable terms are on the left hand side.
2x=-1+9
Add 9 to both sides.
2x=8
Add -1 and 9 to get 8.
x=\frac{8}{2}
Divide both sides by 2.
x=4
Divide 8 by 2 to get 4.
y=-1 x=4
The system is now solved.
