Simplifying
5(4z + -1) + -4(z + 9) = 12(z + 1)

Reorder the terms:
5(-1 + 4z) + -4(z + 9) = 12(z + 1)
(-1 * 5 + 4z * 5) + -4(z + 9) = 12(z + 1)
(-5 + 20z) + -4(z + 9) = 12(z + 1)

Reorder the terms:
-5 + 20z + -4(9 + z) = 12(z + 1)
-5 + 20z + (9 * -4 + z * -4) = 12(z + 1)
-5 + 20z + (-36 + -4z) = 12(z + 1)
