What is the exact value of the sum of these two numbers

Question

There exist two numbers where the difference between three-fifths of either number and ten is exactly three. What is the exact value of the sum of these two numbers

Answer 1

3x/5 -10 = 3

3x -50 =-15

3x =65

x = 65/3 = 21 2/3

10-3y/5 = 3

50 -3y =15

3y = 35

y =35/3 = 11 2/3

x+y = 33 1/3

OR

answers could also be 23 1/3 or 43 1/3, if both numbers are the same
