Answer key · Solve equations involving a symbol for an unknown value
- 1.4 — Take 3 from both sides: n = 7 − 3 = 4.
- 2.5 — Take 9 from both sides: n = 14 − 9 = 5.
- 3.9 — Add 4 to both sides: n = 5 + 4 = 9.
- 4.8 — Divide both sides by 4: n = 32 ÷ 4 = 8.
- 5.6 — Divide both sides by 7: n = 42 ÷ 7 = 6.
- 6.4 — Divide both sides by 6: n = 24 ÷ 6 = 4.
- 7.9 — Subtract 8, then divide by 2: n = (26 − 8) ÷ 2 = 9.
- 8.3 — Subtract 6, then divide by 2: n = (12 − 6) ÷ 2 = 3.
- 9.6 — Subtract 4, then divide by 5: n = (34 − 4) ÷ 5 = 6.
