x=-y+16
Solve x+y=16 for x.
y=-z+20 z=34-m
Solve the second equation for y and the third equation for z.
y=-\left(34-m\right)+20
Substitute 34-m for z in the equation y=-z+20.
y=-14+m
Calculate y from y=-\left(34-m\right)+20.
x=-\left(-14+m\right)+16
Substitute -14+m for y in the equation x=-y+16.
x=30-m
Calculate x from x=-\left(-14+m\right)+16.
x=30-m y=-14+m z=34-m
The system is now solved.
