-2x + 4y + 2z = 8

Solving
-2x + 4y + 2z = 8

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.
-2x + 4y + -4y + 2z = 8 + -4y

Combine like terms: 4y + -4y = 0
-2x + 0 + 2z = 8 + -4y
-2x + 2z = 8 + -4y

Add '-2z' to each side of the equation.
-2x + 2z + -2z = 8 + -4y + -2z

Combine like terms: 2z + -2z = 0
-2x + 0 = 8 + -4y + -2z
-2x = 8 + -4y + -2z
