P=Q/(4R+S)P=Q4R+S

Explanation:

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

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

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

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

After this, divide both sides by Q:
1/P=(4R-S)/Q1P=4RSQ

To get P by itself, set each side to the power of -1 (or flip both fractions):
P=Q/(4R-S)P=Q4RS
