Z=\frac{1}{4}\left(-8\right)
Consider the first equation. Multiply both sides by -8.
Z=-2
Multiply \frac{1}{4} and -8 to get -2.
a=-2
Consider the second equation. Insert the known values of variables into the equation.
b=-2
Consider the third equation. Insert the known values of variables into the equation.
Z=-2 a=-2 b=-2
The system is now solved.
