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

1.
10 — Add 6 to both sides: n = 4 + 6 = 10.
2.
6 — Take 2 from both sides: n = 8 − 2 = 6.
3.
7 — Take 8 from both sides: n = 15 − 8 = 7.
4.
3 — Divide both sides by 2: n = 6 ÷ 2 = 3.
5.
3 — Divide both sides by 6: n = 18 ÷ 6 = 3.
6.
6 — Divide both sides by 9: n = 54 ÷ 9 = 6.
7.
8 — Subtract 1, then divide by 2: n = (17 − 1) ÷ 2 = 8.
8.
7 — Subtract 3, then divide by 4: n = (31 − 3) ÷ 4 = 7.
9.
4 — Subtract 7, then divide by 3: n = (19 − 7) ÷ 3 = 4.
