2x-y+2z=-4,6x-3y+6z=-12,-4x+2y-4z=8

2 x - y + 2 z = - 4, 6 x - 3 y + 6 z = - 12, - 4 x + 2 y - 4 z = 8

x = \frac{- 4 + y - 2 z}{2}

Solution steps

2 x - y + 2 z = - 4 6 x - 3 y + 6 z = - 12 - 4 x + 2 y - 4 z = 8

Isolate

x

for

2 x - y + 2 z = - 4 : x = \frac{- 4 + y - 2 z}{2}

Substitute

x = \frac{- 4 + y - 2 z}{2}

[6 \cdot \frac{- 4 + y - 2 z}{2} - 3 y + 6 z = - 12 - 4 \cdot \frac{- 4 + y - 2 z}{2} + 2 y - 4 z = 8]

Simplify

[- 12 = - 12 8 = 8]

The solutions to the system of equations are:

x = \frac{- 4 + y - 2 z}{2}

f (x) = 2, (x + 3) = 3 (2 x^{7})

1.34 x - 6 y = 0, x + 2 y = 14

x + y + z = - 4, 2 x - y + z = 1

23 x + 29 y = 98, 29 x + 23 y = 110

4 x + 6 y = 12, 2 x + 3 y = 6
