Answer key · Solve equations involving a symbol for an unknown value
- 1.5 — Add 8 to both sides: n = -3 + 8 = 5.
- 2.8 — Add 6 to both sides: n = 2 + 6 = 8.
- 3.11 — Add 2 to both sides: n = 9 + 2 = 11.
- 4.3 — Divide both sides by 4: n = 12 ÷ 4 = 3.
- 5.9 — Divide both sides by 8: n = 72 ÷ 8 = 9.
- 6.2 — Divide both sides by 9: n = 18 ÷ 9 = 2.
- 7.4 — Subtract 5, then divide by 5: n = (25 − 5) ÷ 5 = 4.
- 8.6 — Subtract 8, then divide by 3: n = (26 − 8) ÷ 3 = 6.
- 9.4 — Subtract 7, then divide by 2: n = (15 − 7) ÷ 2 = 4.
