Simplifying
6(3z + -1) + -5(z + 8) = 9(z + 1)

Reorder the terms:
6(-1 + 3z) + -5(z + 8) = 9(z + 1)
(-1 * 6 + 3z * 6) + -5(z + 8) = 9(z + 1)
(-6 + 18z) + -5(z + 8) = 9(z + 1)

Reorder the terms:
-6 + 18z + -5(8 + z) = 9(z + 1)
-6 + 18z + (8 * -5 + z * -5) = 9(z + 1)
-6 + 18z + (-40 + -5z) = 9(z + 1)
