Simplifying
5(3z + -1) + -2(z + 1) = 10(z + 1)

Reorder the terms:
5(-1 + 3z) + -2(z + 1) = 10(z + 1)
(-1 * 5 + 3z * 5) + -2(z + 1) = 10(z + 1)
(-5 + 15z) + -2(z + 1) = 10(z + 1)

Reorder the terms:
-5 + 15z + -2(1 + z) = 10(z + 1)
-5 + 15z + (1 * -2 + z * -2) = 10(z + 1)
-5 + 15z + (-2 + -2z) = 10(z + 1)
