Answer key · Create and solve multi-step linear equations
- 1.2 — Subtract 6: 4x = 8. Divide by 4: x = 2.
- 2.8 — Subtract 7: 3x = 24. Divide by 3: x = 8.
- 3.2 — Subtract 8: 3x = 6. Divide by 3: x = 2.
- 4.5 — Collect x-terms: 4x − 1x = 19 − 4, so 3x = 15, giving x = 5.
- 5.5 — Collect x-terms: 4x − 1x = 18 − 3, so 3x = 15, giving x = 5.
- 6.8 — Collect x-terms: 5x − 1x = 35 − 3, so 4x = 32, giving x = 8.
- 7.13/4 — 4x = 20 − 7 = 13, so x = 13/4 = 13/4.
- 8.15/2 — 2x = 24 − 9 = 15, so x = 15/2 = 15/2.
- 9.1 — 5x = 8 − 3 = 5, so x = 5/5 = 1.
