Answer key · Create and solve multi-step linear equations
- 1.7 — Subtract 7: 4x = 28. Divide by 4: x = 7.
- 2.8 — Subtract 3: 4x = 32. Divide by 4: x = 8.
- 3.6 — Subtract 5: 2x = 12. Divide by 2: x = 6.
- 4.5 — Collect x-terms: 3x − 2x = 9 − 4, so 1x = 5, giving x = 5.
- 5.4 — Collect x-terms: 5x − 3x = 15 − 7, so 2x = 8, giving x = 4.
- 6.3 — Collect x-terms: 4x − 1x = 15 − 6, so 3x = 9, giving x = 3.
- 7.4 — 2x = 11 − 3 = 8, so x = 8/2 = 4.
- 8.1 — 2x = 4 − 2 = 2, so x = 2/2 = 1.
- 9.13/2 — 2x = 18 − 5 = 13, so x = 13/2 = 13/2.
