#P=Q/(4R+S)#

Explanation:

First, multiply 4 by both sides to get:
#Q-PS=4PR#

Next, divide both sides by P:
#Q/P-(PS)/P=(4PR)/P#

This simplifies to:
#Q/P-S=4R#

Then, add S to both sides:
#Q/P=4R-S#

After this, divide both sides by Q:
#1/P=(4R-S)/Q#

To get P by itself, set each side to the power of -1 (or flip both fractions):
#P=Q/(4R-S)#
