Question

David's bowling score is 5 less than 3 times Aaron's score. The sum of their scores is 175. Find the score of each student. Use the variable a for Aaron's score.

Answer 1

The answer is 170 due to the fact that we are taking away

Answer 2

Aaron's score= 45

David's score= 130

Explanation:

Aaron's score = a

David's score= 3a-5

a+(3a-5)= 175

4a-5=175

4a=180

a=45

Aaron's score = 45

David's score=3 × 45 -5= 135-5= 130
