Question 169530: make p the subject of the formula: d=p/l+p
Answer by midwood_trail(310)   (Show Source):
You can put this solution on YOUR website! Make p the subject of the formula: d = p/(l+p)
In other words, solve for p. This is a literal equation.
Multiplying both sides by (l + p), we get:
dl + pd = p
We now subtract pd from both sides of the equation.
This is done to get both p letters on the same side.
dl = p - pd....Do you see that we now have both p letters on the right side?
We now factor the right side.
dl = p(1 - d)
To isolate p, we divide both sides of the equation by the quantity (1 - d).
This quantity is our coefficient (in this case).
dl/(1 - d)
Final answer:
p = dl/(1 - d)
