Consider the third equation. Insert the known values of variables into the equation.
z=\left(-3+10\right)\left(-\left(-3\right)-3\right)
Multiply -2 and -5 to get 10.
z=7\left(-\left(-3\right)-3\right)
Add -3 and 10 to get 7.
z=7\left(3-3\right)
The opposite of -3 is 3.
z=7\times 0
Subtract 3 from 3 to get 0.
z=0
Multiply 7 and 0 to get 0.
a=0
Consider the fourth equation. Insert the known values of variables into the equation.
x=-5 y=-3 z=0 a=0
The system is now solved.
