y=7\left(-6\right)-\left(-6+2\right)
Consider the second equation. Insert the known values of variables into the equation.
y=-42-\left(-6+2\right)
Multiply 7 and -6 to get -42.
y=-42-\left(-4\right)
Add -6 and 2 to get -4.
y=-42+4
Multiply -1 and -4 to get 4.
y=-38
Add -42 and 4 to get -38.
z=-38
Consider the third equation. Insert the known values of variables into the equation.
x=-6 y=-38 z=-38
The system is now solved.
