y=2\left(-85\right)+40
Consider the second equation. Insert the known values of variables into the equation.
y=-170+40
Multiply 2 and -85 to get -170.
y=-130
Add -170 and 40 to get -130.
z=-130
Consider the third equation. Insert the known values of variables into the equation.
x=-85 y=-130 z=-130
The system is now solved.
