Question 628901: Solve for R=dy/d+y for y

I assume your equation is:

because what you posted means

And in this equation the d's cancel out making this a very simple equation. If my assumption is correct, then please put parentheses around multiple-term denominators (and numerators).

First let's get rid of the fraction. Multiplying both sides by d+y we get:

which simplifies to:

Next we get the y terms on one side (and the terms that are not y terms on the other side). We can do this all at once by subtracting Ry from each side:

The terms on the right are not like terms so we cannot subtract them. But they both have a factor of y which we can factor out:

And now we can divide both sides by (d-R):

And, since the y is now all by itself, we are finished!
