-y=9-7
Consider the second equation. Subtract 7 from both sides.
-y=2
Subtract 7 from 9 to get 2.
y=-2
Divide both sides by -1.
2x+7=-2
Consider the first equation. Insert the known values of variables into the equation.
2x=-2-7
Subtract 7 from both sides.
2x=-9
Subtract 7 from -2 to get -9.
x=-\frac{9}{2}
Divide both sides by 2.
x=-\frac{9}{2} y=-2
The system is now solved.
