OpenStudy (isaiah.feynman):

You can subtract the right side from both sides as a start.

OpenStudy (jravenv):

wait what?

OpenStudy (isaiah.feynman):

Subtract the term on the right from both sides.

OpenStudy (jravenv):

you mean the fraction?

OpenStudy (isaiah.feynman):

Yep. Sorry.

OpenStudy (jravenv):

4/n+3

OpenStudy (isaiah.feynman):

No. Rather do a cross multiplication. That's easier.

OpenStudy (isaiah.feynman):

So, \[14(n-4)=10(n+7)\]

OpenStudy (jravenv):

Okay, so what's next?

OpenStudy (isaiah.feynman):

Can you solve for n from here?

OpenStudy (jravenv):

Um, I'm sorry I don't know how..

OpenStudy (isaiah.feynman):

First we distribute the 14 and the 10 through the parentheses. That gives us... \[14n-56=10n+70\]

OpenStudy (isaiah.feynman):

Do you see a way to solve for n?

OpenStudy (jravenv):

Um no I'm sorry! .-.

OpenStudy (isaiah.feynman):

Ever heard of "like terms"?

OpenStudy (jravenv):

Yes. you have to combine like terms but every time I look at the equation my mind goes blank, can you help me to break it down a bit more?

OpenStudy (isaiah.feynman):

Okay, well can you combine the like terms? you add the n's separately and the numbers separately.

OpenStudy (jravenv):

14+24n?

OpenStudy (isaiah.feynman):

It should be 4n=126. Solve for n from here.
