Simplifying
-3(z + 1) + 3(3z + -6) = 5(z + -4) + 14

Reorder the terms:
-3(1 + z) + 3(3z + -6) = 5(z + -4) + 14
(1 * -3 + z * -3) + 3(3z + -6) = 5(z + -4) + 14
(-3 + -3z) + 3(3z + -6) = 5(z + -4) + 14

Reorder the terms:
-3 + -3z + 3(-6 + 3z) = 5(z + -4) + 14
-3 + -3z + (-6 * 3 + 3z * 3) = 5(z + -4) + 14
-3 + -3z + (-18 + 9z) = 5(z + -4) + 14

Reorder the terms:
-3 + -18 + -3z + 9z = 5(z + -4) + 14
