Question

2. Bryan and Lori were each given the same pair of numbers. Bryan's description of the two numbers was: The larger number is 3 more than three times the smaller number, s. Lori's description of the two numbers was: Five times the smaller number decreased by 7 is the larger number. Which equation represents this situation?

Answer 1

5 and 18

Explanation:

The two numbers according to Bryan are x and 3x+3. According to Lori they are x and 5x-7. So we know that x+3x+3=x+5x-7. x and x cancel out. 3 and 7 add to 10. 5x-3x=2x. So 2x=10. X=5 and the other number is 18.
