Answer key · Solve equations involving a symbol for an unknown value

1.
7 — Add 2 to both sides: n = 5 + 2 = 7.
2.
9 — Take 6 from both sides: n = 15 − 6 = 9.
3.
5 — Add 1 to both sides: n = 4 + 1 = 5.
4.
2 — Divide both sides by 6: n = 12 ÷ 6 = 2.
5.
6 — Divide both sides by 2: n = 12 ÷ 2 = 6.
6.
4 — Divide both sides by 7: n = 28 ÷ 7 = 4.
7.
8 — Subtract 5, then divide by 5: n = (45 − 5) ÷ 5 = 8.
8.
4 — Subtract 3, then divide by 2: n = (11 − 3) ÷ 2 = 4.
9.
9 — Subtract 5, then divide by 3: n = (32 − 5) ÷ 3 = 9.
