z-z-z-z-z+z+z+z+z+z=

Solution for z-z-z-z-z+z+z+z+z+z= equation:

Simplifying
z + -1z + -1z + -1z + -1z + z + z + z + z + z = 0

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

Combine like terms: -1z + -1z = -2z
-2z + -1z + z + z + z + z + z = 0

Combine like terms: -2z + -1z = -3z
-3z + z + z + z + z + z = 0

Combine like terms: -3z + z = -2z
-2z + z + z + z + z = 0

Combine like terms: -2z + z = -1z
-1z + z + z + z = 0

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

Combine like terms: z + z = 2z
2z = 0

Solving
2z = 0

Solving for variable 'z'.

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