First things first. Typing in all CAPS is the text communications equivalent of shouting. It is both annoying and rude. Let's all use our inside voices children.

Second thing. Never, never, NEVER (yes I shouted on purpose) give out your e-mail address in a public forum -- especially if you are a minor.

Now for your math problem:

Notice that the answer (the RHS of your equation) is an integer, and that you are going to have to divide something by 3. Now if you divide just 7 by 3, you get a non-integer that will have to be combined with other integers. So just the 7 as the numerator over the 3 won't work. But 2 + 7 is 9 and that is evenly divisible by 3. But so is 4 times 2 is 8 plus 7 is 15. But 15 divided by 3 is 5 plus 8 is only 13. So let's go back to the 2 + 7 as the numerator. That is 9 divided by 3 is 3. That is really all you have to do because order of operations says multiplication first. 3 times 4 is 12 plus 8 is 20
