Introduction

In this article, we will be solving a linear equation to find the value of $P$. The equation given is $324.39 - P + 18.9474 = 373.48$. We will use algebraic methods to isolate the variable $P$ and find its value.

Understanding the Equation

The given equation is a linear equation, which means it is an equation in which the highest power of the variable(s) is 1. In this case, the variable is $P$. The equation is:

$324.39 - P + 18.9474 = 373.48$

Isolating the Variable $P$

To isolate the variable $P$, we need to get all the terms involving $P$ on one side of the equation and the constant terms on the other side. We can do this by adding $P$ to both sides of the equation and then subtracting $18.9474$ from both sides.

Step 1: Add $P$ to both sides of the equation

$324.39 - P + 18.9474 + P = 373.48 + P$

Step 2: Simplify the equation

$324.39 + 18.9474 = 373.48 + P$

Step 3: Combine like terms

$343.3374 = 373.48 + P$

Step 4: Subtract $373.48$ from both sides of the equation

$343.3374 - 373.48 = P$

Step 5: Simplify the equation

$-30.1426 = P$

Conclusion

Therefore, the value of $P$ is $-30.1426$.
