Answer:

{2}

Explanation:

Testing out all values:


3(2)+5=11\\\\6+5=11\\\\\boxed{11=11}

The value of 2 works for the equation given.

All other values do not work, as we will result in a contradiction.


3(3)+5=11\\\\9+5=11\\\\14\\eq 11\\\\\\3(6)+5=11\\\\18+5=11\\\\23\\eq 11\\\\\\3(7)+5=11\\\\21+5=11\\\\26\\eq 11

Hope this helps you.
