1. ## quotient of functions

I forgot what these are called but when it comes to these, i get wayyy lost and just dont know what to do.

$\displaystyle (1 - x)/(1 + x)=100$

Thanks for the help!

These are called equations. Don't be lost my friend, just multiply both sides by $\displaystyle (1+x)$. Then distibute the $\displaystyle 100$, and isolate $\displaystyle x.$

Tell me the answer is $\displaystyle x = -99/100$

Yes.

5. $\displaystyle \frac{1 - x}{1 + x}=100$

$\displaystyle 1-x=100(1+x)$

$\displaystyle 1-x=100+100x$

$\displaystyle 1-100=100x+x$

$\displaystyle -99=101x$

$\displaystyle \frac{-99}{101}=x$

6. EDIT: EDIT: alriiiight. Thanks a whole bunch.
