bobbym,
Well i figured the opposite of the problem was 13+9 which is 22. And i plugged in the numbers: 22-9=13.

bobbym:::::::::
x-9=13 X=22
I think it is right.

Hi everyone!!!
I currently had a lesson on equations. It's been awhile since iv'e practiced about it. I need someone to define or tell me how to do it in the most clearest way.
Or you can just tell me how YOU understand it.I appreciate everyone who helps. Thank you!!!!!!!!!!!!

Hi NFS1:
As bobbym said, you "deduce the expansion of 1/1+cos as far as the term".
This is the way i find it best to figure out. If you ned more help go to aaamath,mathsisfun advanced or an advanced tutoring site.
