Simplifying
5(4z + -1) + -3(z + 7) = 3(z + 1)

Reorder the terms:
5(-1 + 4z) + -3(z + 7) = 3(z + 1)
(-1 * 5 + 4z * 5) + -3(z + 7) = 3(z + 1)
(-5 + 20z) + -3(z + 7) = 3(z + 1)

Reorder the terms:
-5 + 20z + -3(7 + z) = 3(z + 1)
-5 + 20z + (7 * -3 + z * -3) = 3(z + 1)
-5 + 20z + (-21 + -3z) = 3(z + 1)

Reorder the terms:
-5 + -21 + 20z + -3z = 3(z + 1)

Combine like terms: -5 + -21 = -26
-26 + 20z + -3z = 3(z + 1)

Combine like terms: 20z + -3z = 17z
-26 + 17z = 3(z + 1)

Reorder the terms:
-26 + 17z = 3(1 + z)
