2x=-14
Consider the second equation. Combine 4x and -2x to get 2x.
x=\frac{-14}{2}
Divide both sides by 2.
x=-7
Divide -14 by 2 to get -7.
-7-2y=7
Consider the first equation. Insert the known values of variables into the equation.
-2y=7+7
Add 7 to both sides.
-2y=14
Add 7 and 7 to get 14.
y=\frac{14}{-2}
Divide both sides by -2.
y=-7
Divide 14 by -2 to get -7.
x=-7 y=-7
The system is now solved.
