Answer key · Create and solve multi-step linear equations
- 1.8 — Subtract 2: 5x = 40. Divide by 5: x = 8.
- 2.8 — Subtract 6: 3x = 24. Divide by 3: x = 8.
- 3.5 — Subtract 9: 2x = 10. Divide by 2: x = 5.
- 4.8 — Collect x-terms: 5x − 1x = 33 − 1, so 4x = 32, giving x = 8.
- 5.8 — Collect x-terms: 4x − 1x = 28 − 4, so 3x = 24, giving x = 8.
- 6.2 — Collect x-terms: 6x − 3x = 10 − 4, so 3x = 6, giving x = 2.
- 7.4/5 — 5x = 12 − 8 = 4, so x = 4/5 = 4/5.
- 8.5/3 — 3x = 9 − 4 = 5, so x = 5/3 = 5/3.
- 9.3 — 5x = 23 − 8 = 15, so x = 15/5 = 3.
