solve for x?

OpenStudy (anonymous):

I'm assuming. All it says is to solve the equation. :-(

OpenStudy (anonymous):

yeah, same thing ^^

OpenStudy (anonymous):

alright, do you know how to simplify the left hand term?

OpenStudy (anonymous):

By the LCD?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Which is (x+5)(x-5)

OpenStudy (anonymous):

I get =

OpenStudy (anonymous):

inform me what you get after simplyfying the left hand term..

OpenStudy (anonymous):

7x - 35 - 4x + 20

OpenStudy (anonymous):

that's -20, i guess

OpenStudy (anonymous):

Oh!!!

OpenStudy (anonymous):

So that's where I've been messing up...

OpenStudy (anonymous):

the numerator will be 7x-35-4x-20=3x-55

OpenStudy (anonymous):

i think you can do the rest then? answer should come x=23

OpenStudy (anonymous):

3x - 55 = 14 3x = 69 x = 23

OpenStudy (anonymous):

Yess!! Thank you very much!
