SUMMARY
The equation y = 9/4 - 3(3/2) simplifies to y = -9/4. A common mistake occurs when incorrectly changing signs during calculations. The correct steps involve first multiplying 3 by 3/2 to get 9/2, and then subtracting this from 9/4. The final result confirms that y equals -9/4, highlighting the importance of careful sign management in arithmetic operations.
