... if you get 1/2 then you are correct
Assuming (as above) that A is larger than B, start by turning the problem statement into a formula.
"The sum of two numbers is 3 times their positive difference" then becomes
"A + B = 3 * (A - B)".
Then proceed (as above) to expand 3 * (A - B) and then combine all A terms on one side and all B terms on the other.
You can easily satisfy the initial assumption by simply labeling the larger number as A and the smaller as B.
