2z-(1-z)=-z

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

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

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

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

Solving
-1 + 3z = -1z

Solving for variable 'z'.

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

Add 'z' to each side of the equation.
-1 + 3z + z = -1z + z

Combine like terms: 3z + z = 4z
-1 + 4z = -1z + z

Combine like terms: -1z + z = 0
-1 + 4z = 0

Add '1' to each side of the equation.
-1 + 1 + 4z = 0 + 1

Combine like terms: -1 + 1 = 0
0 + 4z = 0 + 1
4z = 0 + 1

Combine like terms: 0 + 1 = 1
4z = 1

Divide each side by '4'.
z = 0.25

Simplifying
z = 0.25
