P 144p Y Solve For P

Solving for p: A Comprehensive Guide to Algebraic Equations

The equation "p + 144p = y" presents a fundamental algebraic problem: solving for an unknown variable. While seemingly simple, mastering this type of equation builds a strong foundation for more complex algebraic manipulations. This comprehensive guide will walk you through various methods to solve for 'p', explain the underlying principles, and provide practical examples to solidify your understanding. We'll also explore the significance of this type of problem in different mathematical contexts.

Understanding the Equation: p + 144p = y

Before diving into the solution, let's break down the equation itself. We have:

• p: This represents our unknown variable, the value we need to find.
• 144p: This is a term representing 144 multiplied by 'p'.
• y: This is a known constant, a given value. The problem essentially asks: "If the sum of 'p' and 144 times 'p' equals 'y', what is the value of 'p'?"

The equation is a linear equation, meaning the highest power of the variable 'p' is 1. This simplifies the solving process significantly compared to higher-order equations.

Method 1: Combining Like Terms

The most straightforward approach is to combine the like terms involving 'p'. Both 'p' and '144p' are terms containing 'p', and therefore can be added together:

p + 144p = 145p

This simplifies our equation to:

145p = y

Method 2: The Distributive Property (Less Common but Illustrative)

Although less efficient for this specific equation, understanding the distributive property is crucial for solving more complex algebraic problems. We can rewrite the original equation as:

1p + 144p = y

Now, we can factor out 'p':

p(1 + 144) = y

This simplifies to:

145p = y

Solving for p: Isolating the Variable

Both methods lead us to the same simplified equation: 145p = y. The final step is to isolate 'p' by itself on one side of the equation. To do this, we perform the inverse operation of multiplication, which is division. We divide both sides of the equation by 145:

(145p)/145 = y/145

This simplifies to:

p = y/145

This is our solution. The value of 'p' is equal to 'y' divided by 145.

Practical Examples with Numerical Values for y

Let's solidify our understanding with some numerical examples.

Example 1: y = 1450

If y = 1450, then:

p = 1450/145

p = 10

Therefore, if the sum of 'p' and 144 times 'p' equals 1450, then 'p' equals 10. We can verify this: 10 + 144(10) = 1450.

Example 2: y = 290

If y = 290, then:

p = 290/145

p = 2

Therefore, if the sum of 'p' and 144 times 'p' equals 290, then 'p' equals 2. Let's verify: 2 + 144(2) = 290.

Example 3: y = 0

If y = 0, then:

p = 0/145

p = 0

This shows that if the sum is zero, then p must also be zero.
