I don't know which box you want me to put the answer in but: 2(z + 1) - 4(z - 4) ≤ 2(z + 5) *Distribute* 2z + 2 - 4z - 16 ≤ 2z + 10 *Combine Like Terms* -2z - 14 ≤ 2z + 10 *Add 14 to BOTH sides* -2z ≤ 2z + 24 *Subtract 2z from BOTH sides* -4z ≤ 24 *Divide BOTH sides by -4* z ≥ -6 Edit: I forgot that dividing or multiplying by a negative flips the inequality.
