too easy.
Ok, we know X equals 6. Therefore Y equals 7 because Y is one place after X in the alphabet. So 1 + 6 = 7. Y=7
Now that we have the difficult part out of the way we can proceed.
9(7) + 6(6)(7)=30
97 + 667 = 30
NO! It equals 764.
The answer is 764. The person that said it equaled 30 is obviously a complete and utter imbicile. They're probably a virgin too. (Go back to high school brainiac!)
You're welcome.
