Solution for -[7z-(12z+8)]=8+(4z+0) equation:


Simplifying
-1[7z + -1(12z + 8)] = 8 + (4z + 0)

Reorder the terms:
-1[7z + -1(8 + 12z)] = 8 + (4z + 0)
-1[7z + (8 * -1 + 12z * -1)] = 8 + (4z + 0)
-1[7z + (-8 + -12z)] = 8 + (4z + 0)

Reorder the terms:
-1[-8 + 7z + -12z] = 8 + (4z + 0)

Combine like terms: 7z + -12z = -5z
-1[-8 + -5z] = 8 + (4z + 0)
[-8 * -1 + -5z * -1] = 8 + (4z + 0)
[8 + 5z] = 8 + (4z + 0)

Reorder the terms:
8 + 5z = 8 + (0 + 4z)
Remove the zero:
8 + 5z = 8 + (4z)
8 + 5z = 8 + (4z)

Add '-8' to each side of the equation.
8 + -8 + 5z = 8 + -8 + (4z)

Combine like terms: 8 + -8 = 0
0 + 5z = 8 + -8 + (4z)
5z = 8 + -8 + (4z)

Combine like terms: 8 + -8 = 0
5z = 0 + (4z)
5z = (4z)

Solving
5z = (4z)

Solving for variable 'z'.

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

Add '(-4z)' to each side of the equation.
5z + (-4z) = (4z) + (-4z)

Combine like terms: 5z + (-4z) = 1z
1z = (4z) + (-4z)

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

Divide each side by '1'.
z = 0

Simplifying
