(x-5)/(x^2+x)=-12/(x^2-1)

Does the subject line imply the instructions for this? That is, are you supposed to be solving this rational equation? If not, what are the instructions? If so, what are your thoughts? What have you tried? How far have you gotten? Where are you stuck?

For instance, you first cross-multiplied to clear the fractions, multiplied everything out, moved everything over to one side of the "equals" sign, and... then what?

Please be complete. Thank you!
