Answer: The two numbers are 35 and 5
Step-by-step explanation:
Let first positive number be 7x
second positive number be x
If 15 is added to both the numbers, then one of the new number becomes 5/2 times the other.
5/2 (x+15) = 7x + 15
5x /2 + 75/2 = 7x+ 15
5x/2 -7x = 15 - 75/2
5x - 14x = 30 - 75
- 9x = -45
x = 5
First positive number = 7x =7×5 =35
Second positive number = 5
