-[7z-(18z+6)]=6+(10z+7)

Solution for -[7z-(18z+6)]=6+(10z+7) equation:

Simplifying
-1[7z + -1(18z + 6)] = 6 + (10z + 7)

Reorder the terms:
-1[7z + -1(6 + 18z)] = 6 + (10z + 7)
-1[7z + (6 * -1 + 18z * -1)] = 6 + (10z + 7)
-1[7z + (-6 + -18z)] = 6 + (10z + 7)

Reorder the terms:
-1[-6 + 7z + -18z] = 6 + (10z + 7)

Combine like terms: 7z + -18z = -11z
-1[-6 + -11z] = 6 + (10z + 7)
[-6 * -1 + -11z * -1] = 6 + (10z + 7)
[6 + 11z] = 6 + (10z + 7)

Reorder the terms:
6 + 11z = 6 + (7 + 10z)

Remove parenthesis around (7 + 10z)
6 + 11z = 6 + 7 + 10z

Combine like terms: 6 + 7 = 13
6 + 11z = 13 + 10z

Solving
6 + 11z = 13 + 10z

Solving for variable 'z'.

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

Add '-10z' to each side of the equation.
6 + 11z + -10z = 13 + 10z + -10z

Combine like terms: 11z + -10z = 1z
6 + 1z = 13 + 10z + -10z

Combine like terms: 10z + -10z = 0
6 + 1z = 13 + 0
6 + 1z = 13

Add '-6' to each side of the equation.
6 + -6 + 1z = 13 + -6

Combine like terms: 6 + -6 = 0
0 + 1z = 13 + -6
1z = 13 + -6

Combine like terms: 13 + -6 = 7
1z = 7

Divide each side by '1'.
z = 7

Simplifying
z = 7
