Question #d0c0d

Answer 1

`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)`
