Answer:
The smaller number can be 8 or
.
Step-by-step explanation:
Consider the provided information.
let the larger number is x and the smaller number is y
A positive number is 3 times another number.

If we add 2 to the larger and 5 to the smaller, then one of them becomes 2 times the other.
Case I: If 2nd number is 2 times to the first number.

Substitute the value of x.


Now substitute the value of y in 


Therefore, the smaller number is 8.
Case II: If 1st number is 2 times to the second number.

Substitute the value of x.




Therefore, the smaller number is
.
Both have the same slope 1 in front of X and parallel to each other.
