-16 + 4z = 6 + -2z

Solving for variable 'z'.

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

Add '2z' to each side of the equation.
-16 + 4z + 2z = 6 + -2z + 2z

Combine like terms: 4z + 2z = 6z
-16 + 6z = 6 + -2z + 2z

Combine like terms: -2z + 2z = 0
-16 + 6z = 6 + 0
-16 + 6z = 6

Add '16' to each side of the equation.
-16 + 16 + 6z = 6 + 16

Combine like terms: -16 + 16 = 0
0 + 6z = 6 + 16
6z = 6 + 16

Combine like terms: 6 + 16 = 22
6z = 22

Divide each side by '6'.
z = 3.666666667
