# Thread: equation with rational expression help please

1. ## equation with rational expression help please

I'm trying to do some homework and the book doesn't really cover a lot in the examples and one problem is giving me trouble, if anyone could walk me through how to do it I would appreciate it.

2/(1-x)-1/x=7/6

2/(1-x)-1/x=7/6
$\frac{2}{(1-x)}-\frac{1}{x}=\frac{7}{6}$

You want a rational solution?

Multiply both sides by $x(1-x)$

Actually, multiplying both sides by $6x(1 - x)$ is a bit nicer, as it clears all of the fractions.
