6 + 1.5z = -8 + 3.5z

Solving for variable 'z'.

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

Add '-3.5z' to each side of the equation.
6 + 1.5z + -3.5z = -8 + 3.5z + -3.5z

Combine like terms: 1.5z + -3.5z = -2z
6 + -2z = -8 + 3.5z + -3.5z

Combine like terms: 3.5z + -3.5z = 0.0
6 + -2z = -8 + 0.0
6 + -2z = -8

Add '-6' to each side of the equation.
6 + -6 + -2z = -8 + -6

Combine like terms: 6 + -6 = 0
0 + -2z = -8 + -6
-2z = -8 + -6

Combine like terms: -8 + -6 = -14
-2z = -14

Divide each side by '-2'.
z = 7

Simplifying
z = 7
