(t+24)/(t^2-t-56)+7/(t-8)=3/(t+7)

I do know that (t^2-t-56) can be factored out to (t-8)(t+7)

so I have the equation as (t+24/(t-8)(t+7) +7(t+7)/(t-8)(t+7)-3(x-8)/(t-8)(t+7)

is this correct ot what am I doing wrong?

I don't understand the rest

so multipy both sides by

(t-8)(t+7)

(t-24) + 7(t+7)=3(t-8)

solve for t.

The choices are:

a.)-97/5

b.)122/5

c.)-13

d.)-13/5

**drwls**, Sunday, October 12, 2008 at 3:04pmWell you had an error in your last equation, which should read

(t+24) + 7(t+7) = 3(t-8)

which becomes

5t = -97

so your answer is correct anyway. You made two cancelling mistakes, or a typing error.
