Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
Begin by finding the LCD for the entire problem, which is fsr.
Multiply both sides of the equation by fsr:
In the first fraction, the f divides out,
in the second, the s divides out, and
in the third fraction, the r divides out.
What is left will be:
You are solving for s, so get the s terms all on the left side by subtracting fs from each side:
Get the s in one place by factoring out the s:
Last, divide both sides by (r-f):
Final answer:
R^2 at SCC
