Bobcats scored 2x - 7 points
Huskies scored 5x - 3 points
Assuming Huskies scored more than Bobcats, the difference between them is:
D =(5x - 3) - (2x - 7)
Operating:
D = 5x - 3 - 2x + 7
Recall the negative sign changes the signs of the parentheses' contents.
Simplifying:
D = 3x + 4
The Huskies scored 3x + 4 more points than The Bobcats
