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 $\displaystyle x.$
