5 + -30z + 5(9 + 7z) = -1z + 4(z + -7)
5 + -30z + (9 * 5 + 7z * 5) = -1z + 4(z + -7)
5 + -30z + (45 + 35z) = -1z + 4(z + -7)

Reorder the terms:
5 + 45 + -30z + 35z = -1z + 4(z + -7)

Combine like terms: 5 + 45 = 50
50 + -30z + 35z = -1z + 4(z + -7)

Combine like terms: -30z + 35z = 5z
50 + 5z = -1z + 4(z + -7)

Reorder the terms:
50 + 5z = -1z + 4(-7 + z)
50 + 5z = -1z + (-7 * 4 + z * 4)
50 + 5z = -1z + (-28 + 4z)
