Solution for 4z-2[-(z+3)]=20-[-(3z-8)] equation:


Simplifying
4z + -2[-1(z + 3)] = 20 + -1[-1(3z + -8)]

Reorder the terms:
4z + -2[-1(3 + z)] = 20 + -1[-1(3z + -8)]
4z + -2[(3 * -1 + z * -1)] = 20 + -1[-1(3z + -8)]
4z + -2[(-3 + -1z)] = 20 + -1[-1(3z + -8)]
4z + [-3 * -2 + -1z * -2] = 20 + -1[-1(3z + -8)]
4z + [6 + 2z] = 20 + -1[-1(3z + -8)]

Reorder the terms:
6 + 4z + 2z = 20 + -1[-1(3z + -8)]

Combine like terms: 4z + 2z = 6z
6 + 6z = 20 + -1[-1(3z + -8)]

Reorder the terms:
6 + 6z = 20 + -1[-1(-8 + 3z)]
6 + 6z = 20 + -1[(-8 * -1 + 3z * -1)]
6 + 6z = 20 + -1[(8 + -3z)]
6 + 6z = 20 + [8 * -1 + -3z * -1]
6 + 6z = 20 + [-8 + 3z]

Combine like terms: 20 + -8 = 12
6 + 6z = 12 + 3z

Solving
6 + 6z = 12 + 3z

Solving for variable 'z'.

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

Add '-3z' to each side of the equation.
6 + 6z + -3z = 12 + 3z + -3z
