Can You Solve the Pattern

Can you figure out the pattern? What is the missing number?
You got it anonymous. The pattern is A*B - 20 = C. So the first row is 7*4 - 20 = 8. The second is 3*9 - 20 = 7. The third is 6*5 - 20 = 10. So that means the last row, "?*8 - 20 = 4" indicates the missing number is 3.
Is there another pattern where the answer is 11? I would guess it's possible, but I'm not seeing it.
Leave your answer or, if you want to post a question of your own, send me an e-mail. Look in the about section to find my e-mail address. If it's new, I'll post it soon.
