Simplifying
5(4z + -1) + -5(z + 6) = 12(z + 1)

Reorder the terms:
5(-1 + 4z) + -5(z + 6) = 12(z + 1)
(-1 * 5 + 4z * 5) + -5(z + 6) = 12(z + 1)
(-5 + 20z) + -5(z + 6) = 12(z + 1)

Reorder the terms:
-5 + 20z + -5(6 + z) = 12(z + 1)
-5 + 20z + (6 * -5 + z * -5) = 12(z + 1)
-5 + 20z + (-30 + -5z) = 12(z + 1)
