y=2-7\left(9-4\right)
Consider the second equation. Insert the known values of variables into the equation.
y=2-7\times 5
Subtract 4 from 9 to get 5.
y=2-35
Multiply -7 and 5 to get -35.
y=-33
Subtract 35 from 2 to get -33.
z=-33
Consider the third equation. Insert the known values of variables into the equation.
x=4 y=-33 z=-33
The system is now solved.
