Simplifying
4(3z + -1) + -3(z + 3) = 6(z + 1)

Reorder the terms:
4(-1 + 3z) + -3(z + 3) = 6(z + 1)
(-1 * 4 + 3z * 4) + -3(z + 3) = 6(z + 1)
(-4 + 12z) + -3(z + 3) = 6(z + 1)

Reorder the terms:
-4 + 12z + -3(3 + z) = 6(z + 1)
-4 + 12z + (3 * -3 + z * -3) = 6(z + 1)
-4 + 12z + (-9 + -3z) = 6(z + 1)

Reorder the terms:
-4 + -9 + 12z + -3z = 6(z + 1)

Combine like terms: -4 + -9 = -13
-13 + 12z + -3z = 6(z + 1)

Combine like terms: 12z + -3z = 9z
