Simplifying
4(6z + -1) + -2(z + 8) = 9(z + 1)

Reorder the terms:
4(-1 + 6z) + -2(z + 8) = 9(z + 1)
(-1 * 4 + 6z * 4) + -2(z + 8) = 9(z + 1)
(-4 + 24z) + -2(z + 8) = 9(z + 1)

Reorder the terms:
-4 + 24z + -2(8 + z) = 9(z + 1)
-4 + 24z + (8 * -2 + z * -2) = 9(z + 1)
-4 + 24z + (-16 + -2z) = 9(z + 1)
