[

x+2y−3z=−13

4y+2z=2

−x+y−z=−2

]

Isolate y for 4y+2z=2: y=1−z2

Substitute y=1−z2

[

x+2· 1−z2 −3z=−13

−x+1−z2 −z=−2

]

Simplify

[

x+1−4z=−13

−x+1−3z2 =−2

]

Isolate x for x+1−4z=−13: x=4z−14

Substitute x=4z−14

[

−(4z−14)+1−3z2 =−2

]

Simplify

[

1−11z2 +14=−2

]

Isolate z for 1−11z2 +14=−2: z=3

For x=4z−14

Substitute z=3

x=4· 3−14

Simplify

x=−2

For y=1−z2

Substitute x=−2, z=3

y=1−32

1−32 =−1

y=−1

The solutions to the system of equations are:

x=−2, y=−1, z=3
