y=\frac{2}{-2}
Consider the first equation. Divide both sides by -2.
y=-1
Divide 2 by -2 to get -1.
z=-1
Consider the second equation. Insert the known values of variables into the equation.
a=-1
Consider the third equation. Insert the known values of variables into the equation.
y=-1 z=-1 a=-1
The system is now solved.
