Simplifying
6(5z + -1) + -4(z + 1) = 15(z + 1)

Reorder the terms:
6(-1 + 5z) + -4(z + 1) = 15(z + 1)
(-1 * 6 + 5z * 6) + -4(z + 1) = 15(z + 1)
(-6 + 30z) + -4(z + 1) = 15(z + 1)

Reorder the terms:
-6 + 30z + -4(1 + z) = 15(z + 1)
-6 + 30z + (1 * -4 + z * -4) = 15(z + 1)
-6 + 30z + (-4 + -4z) = 15(z + 1)
