z-2(1-z)-z=

Solution for z-2(1-z)-z= equation:

Simplifying
z + -2(1 + -1z) + -1z = 0
z + (1 * -2 + -1z * -2) + -1z = 0
z + (-2 + 2z) + -1z = 0

Reorder the terms:
-2 + z + 2z + -1z = 0

Combine like terms: z + 2z = 3z
-2 + 3z + -1z = 0

Combine like terms: 3z + -1z = 2z
-2 + 2z = 0

Solving
-2 + 2z = 0

Solving for variable 'z'.

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

Add '2' to each side of the equation.
-2 + 2 + 2z = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 2z = 0 + 2
2z = 0 + 2

Combine like terms: 0 + 2 = 2
2z = 2

Divide each side by '2'.
z = 1

Simplifying
z = 1
