x=\frac{-20}{2}
Consider the first equation. Divide both sides by 2.
x=-10
Divide -20 by 2 to get -10.
y=-7
Consider the second equation. Subtract 3 from -4 to get -7.
z=-7
Consider the third equation. Insert the known values of variables into the equation.
x=-10 y=-7 z=-7
The system is now solved.
