Answer key · Solve two-step equations with whole numbers
- 1.4 — Subtract 2, then divide by 2: n = (10 − 2) ÷ 2 = 4.
- 2.4 — Subtract 5, then divide by 5: n = (25 − 5) ÷ 5 = 4.
- 3.4 — Subtract 3, then divide by 5: n = (23 − 3) ÷ 5 = 4.
- 4.8 — Add 9, then divide by 4: n = (23 + 9) ÷ 4 = 8.
- 5.5 — Add 5, then divide by 2: n = (5 + 5) ÷ 2 = 5.
- 6.2 — Add 9, then divide by 3: n = (-3 + 9) ÷ 3 = 2.
- 7.8 — Combine like terms: 7n + 7 = 63, so n = (63 − 7) ÷ 7 = 8.
- 8.3 — Combine like terms: 6n + 6 = 24, so n = (24 − 6) ÷ 6 = 3.
- 9.5 — Combine like terms: 6n + 7 = 37, so n = (37 − 7) ÷ 6 = 5.
