Answer key · Create and solve multi-step linear equations
- 1.7 — Subtract 7: 6x = 42. Divide by 6: x = 7.
- 2.3 — Subtract 2: 4x = 12. Divide by 4: x = 3.
- 3.9 — Subtract 6: 6x = 54. Divide by 6: x = 9.
- 4.5 — Collect x-terms: 3x − 1x = 18 − 8, so 2x = 10, giving x = 5.
- 5.2 — Collect x-terms: 4x − 3x = 10 − 8, so 1x = 2, giving x = 2.
- 6.7 — Collect x-terms: 4x − 2x = 19 − 5, so 2x = 14, giving x = 7.
- 7.5 — 2x = 14 − 4 = 10, so x = 10/2 = 5.
- 8.3 — 4x = 19 − 7 = 12, so x = 12/4 = 3.
- 9.7/2 — 4x = 19 − 5 = 14, so x = 14/4 = 7/2.
