Homework Help: math-rational equations

Posted by Kay on Wednesday, July 1, 2009 at 7:46pm.

how do I solve 5/x-3+3/x+3=7x/x^2-9
please explain in detail, I am having trouble once I get to the part where I need to simplify. I have so far the LCD is x^2-9
then the equation changes to (x^2-9) 5/x-3+(x^2-9) 3/x+3=(x^2-9) 7x/x^2-9
or (x+3)*5(x-3)*3=7x after this I'm stuck. Thank you in advance.
