2(2z-1)-2(2-2z)=12

Solution for 2(2z-1)-2(2-2z)=12 equation:

Simplifying
2(2z + -1) + -2(2 + -2z) = 12

Reorder the terms:
2(-1 + 2z) + -2(2 + -2z) = 12
(-1 * 2 + 2z * 2) + -2(2 + -2z) = 12
(-2 + 4z) + -2(2 + -2z) = 12
-2 + 4z + (2 * -2 + -2z * -2) = 12
-2 + 4z + (-4 + 4z) = 12

Reorder the terms:
-2 + -4 + 4z + 4z = 12

Combine like terms: -2 + -4 = -6
-6 + 4z + 4z = 12

Combine like terms: 4z + 4z = 8z
-6 + 8z = 12

Solving
-6 + 8z = 12

Solving for variable 'z'.

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

Add '6' to each side of the equation.
-6 + 6 + 8z = 12 + 6

Combine like terms: -6 + 6 = 0
0 + 8z = 12 + 6
8z = 12 + 6

Combine like terms: 12 + 6 = 18
8z = 18

Divide each side by '8'.
z = 2.25

Simplifying
z = 2.25
