2+2x=x+1z z=x\times 2
Substitute 2 for y in the second and third equation.
x=-2+z
Solve 2+2x=x+1z 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 x=2 z=4
The system is now solved.
