Simplifying
6(5z + -1) + -3(z + 2) = 20(z + 1)

Reorder the terms:
6(-1 + 5z) + -3(z + 2) = 20(z + 1)
(-1 * 6 + 5z * 6) + -3(z + 2) = 20(z + 1)
(-6 + 30z) + -3(z + 2) = 20(z + 1)

Reorder the terms:
-6 + 30z + -3(2 + z) = 20(z + 1)
-6 + 30z + (2 * -3 + z * -3) = 20(z + 1)
-6 + 30z + (-6 + -3z) = 20(z + 1)
