Solving
1z = 15z

Solving for variable 'z'.

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

Add '-15z' to each side of the equation.
1z + -15z = 15z + -15z

Combine like terms: 1z + -15z = -14z
-14z = 15z + -15z

Combine like terms: 15z + -15z = 0
-14z = 0

Divide each side by '-14'.
z = 0

Simplifying
z = 0
