x=y+4
Solve x-y=4 for x.
y+4+z=3
Substitute y+4 for x in the equation x+z=3.
y=z-1 z=-1-y
Solve the second equation for y and the third equation for z.
z=-1-\left(z-1\right)
Substitute z-1 for y in the equation z=-1-y.
z=0
Solve z=-1-\left(z-1\right) for z.
y=0-1
Substitute 0 for z in the equation y=z-1.
y=-1
Calculate y from y=0-1.
x=-1+4
Substitute -1 for y in the equation x=y+4.
x=3
Calculate x from x=-1+4.
x=3 y=-1 z=0
The system is now solved.
