Final answer:
To solve the equation Q = r + 8 - t for r, subtract 8 and t from both sides.
Step-by-step explanation:
To solve the equation Q = r + 8 - t for r, you need to isolate r on one side of the equation. Here are the steps:
- Subtract 8 and t from both sides of the equation: Q - 8 - t = r
- Therefore, r = Q - 8 - t
