Simplifying
6(3z + -1) + -2(z + 9) = 9(z + 1)

Reorder the terms:
6(-1 + 3z) + -2(z + 9) = 9(z + 1)
(-1 * 6 + 3z * 6) + -2(z + 9) = 9(z + 1)
(-6 + 18z) + -2(z + 9) = 9(z + 1)

Reorder the terms:
-6 + 18z + -2(9 + z) = 9(z + 1)
-6 + 18z + (9 * -2 + z * -2) = 9(z + 1)
-6 + 18z + (-18 + -2z) = 9(z + 1)
