David's bowling score is 5 less than 3 times Aaron's score. The sum of their scores is 215. Find the score of each student.

d=David's bowling score
a=Aaron's bowling score

d=3a-5

a+d=215

If:
a+d=215
d=215-a

If d=215-a
215-a=3a-5
215+5=3a+a
220=4a
a=220/4
**a=55 **
**
**If a=55,
d=215-55
d=160

**
David's bowling score was 160.
Aaron's bowling score was 55. **
