y=x+1
Solve x+1=y for y.
x+1+1=z
Substitute x+1 for y in the equation y+1=z.
x=-2+z
Solve x+1+1=z for x.
z=2\left(-2+z\right)
Substitute -2+z for x in the equation z=2x.
z=4
Solve z=2\left(-2+z\right) for z.
x=-2+4
Substitute 4 for z in the equation x=-2+z.
x=2
Calculate x from x=-2+4.
y=2+1
Substitute 2 for x in the equation y=x+1.
y=3
Calculate y from y=2+1.
x=2 y=3 z=4
The system is now solved.
