do you mean like this:
720/(V30) + 720/(V+30) = 10
Get a common denominator of
(v30)(v+30)
then multiplying both sides by that, then
(v30)(v+30)X 720(V+30) + (v30)(v+30) X 720(V30)=(v30)(v+30)X 10(v30)(v+30)
then multily out, and solve for v.
720(v30)+720(v+30)=10
720v21600+720v+21600=10
1440v=10
v=144
The right side: you have to multipy both sides by (v30)(v+30
720(v30)+720(v+30)=10(v30)(v+30)
You will get a quadratic.
As an aside, 1440v if it equalled 10, does not give v=144. It gives 1/144.
