On Saturday, Lukas drove 4x - 5 miles. On Sunday, he drove 3x - 10 miles. What is the difference in miles driven?

The difference in miles driven is given by the expression (4x - 5) - (3x - 10).

This simplifies to 4x - 5 - 3x + 10.
Combining like terms, we get x + 5.
Therefore, the difference in miles driven is x + 5 miles.
