I want this equation to be solved for V

I want to see world peace. Ok, lacking that, is it too much to want for a just a little Lamborghini for Xmas? Maybe just win the lottery?

The fact is, there are all sorts of things we may want, but will never happen.

If R, T, and W are unknowns (Is RW also an unknown, or do you just not understand that MATLAB does not have implicit multiplication.) Anyway, if you then want to solve for V as an algebraic function of the other unknowns, then forget it. Unless of course you happen to have skill at using a magic wand. But mathematics cannot help you here. Not all problems you can write down have a solution. In fact, it can be proven that most such problems do NOT have an algebraic solution.

Remember that your problem, even if a solution did exist, would implicitly reduce to a high order polynomial in V. And what do we know about polynomials of degree 5 or higher? There is no algebraic solution to be found for that general polynomial.

So you might want to set your sights lower. Look for a problem that may even have a solution.

If, for exmple, you happen to have values for ALL of the other parameters, then you can use a numerical solver to search for solutions. Remember there will likely be multiple solutions, and a numerical solver can search for only one at a time.
