Simplifying
5(3z + -1) + -3(z + 4) = 9(z + 1)

Reorder the terms:
5(-1 + 3z) + -3(z + 4) = 9(z + 1)
(-1 * 5 + 3z * 5) + -3(z + 4) = 9(z + 1)
(-5 + 15z) + -3(z + 4) = 9(z + 1)

Reorder the terms:
-5 + 15z + -3(4 + z) = 9(z + 1)
-5 + 15z + (4 * -3 + z * -3) = 9(z + 1)
-5 + 15z + (-12 + -3z) = 9(z + 1)
