Step-by-step explanation:

As far as I know, the best way to solve this it to guess and check. You can make some logical inferences, for instance that you probably won't be dividing or multiplying 5 and 7, as the resulting number would either not be an integer or would be too large. Thinking like this, you can find that $7+2\times(7-5)\div 1=7+4\div 1=11$. Hope this helps!
