v/(v+5) + 1/(v-4) = 1
(v+5)(v-4) [v/(v+5) + 1/(v-4) = 1]
v(v-4) + (v+5) = (v+5)(v-4)
v^2 - 4v + v + 5 = v^2 + v - 20
-4v = -25
v = 25/4

(v/v+5) + (1/v-4) = 1....?
First convert the two expressions by the Common denominator (v+5)(v-4)

v(v-4) + 1(v+5) /(v+5)(v-4) = v^2 -4v + v + 5/ (v+5)(v-4)
= v^2 -4v + v + 5
= after factoring v^2 -3v + 5/(v+5)(v-4) =1

This is the proof not solving for v.

Well, let's see......1X1=1....so, if you take the equation you need help with....it's quite simple....as a matter of fact it is so simple....a complex, highly intellectual person like myself, may not be able to stoop that low in my mental capacity to answer your quagmire!
