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

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

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