Simplifying
4(5z + -1) + -4(z + 8) = 13(z + 1)

Reorder the terms:
4(-1 + 5z) + -4(z + 8) = 13(z + 1)
(-1 * 4 + 5z * 4) + -4(z + 8) = 13(z + 1)
(-4 + 20z) + -4(z + 8) = 13(z + 1)

Reorder the terms:
-4 + 20z + -4(8 + z) = 13(z + 1)
-4 + 20z + (8 * -4 + z * -4) = 13(z + 1)
-4 + 20z + (-32 + -4z) = 13(z + 1)
