Simplifying
2(6z + -1) + -4(z + 4) = 5(z + 1)

Reorder the terms:
2(-1 + 6z) + -4(z + 4) = 5(z + 1)
(-1 * 2 + 6z * 2) + -4(z + 4) = 5(z + 1)
(-2 + 12z) + -4(z + 4) = 5(z + 1)

Reorder the terms:
-2 + 12z + -4(4 + z) = 5(z + 1)
-2 + 12z + (4 * -4 + z * -4) = 5(z + 1)
-2 + 12z + (-16 + -4z) = 5(z + 1)
