Simplifying
5(4z + -1) + -2(z + 7) = 13(z + -1)

Reorder the terms:
5(-1 + 4z) + -2(z + 7) = 13(z + -1)
(-1 * 5 + 4z * 5) + -2(z + 7) = 13(z + -1)
(-5 + 20z) + -2(z + 7) = 13(z + -1)

Reorder the terms:
-5 + 20z + -2(7 + z) = 13(z + -1)
-5 + 20z + (7 * -2 + z * -2) = 13(z + -1)
-5 + 20z + (-14 + -2z) = 13(z + -1)
