Introduction

In mathematics, equations are used to represent relationships between variables. Solving for a variable in an equation involves isolating that variable on one side of the equation. In this article, we will use the equation $$p = u + 9$$ to find the value of $$p$$ when $$u = 1$$. This will involve substituting the given value of $$u$$ into the equation and solving for $$p$$.

The Equation p = u + 9

The equation $$p = u + 9$$ is a linear equation, where $$p$$ and $$u$$ are variables and $$9$$ is a constant. This equation states that the value of $$p$$ is equal to the value of $$u$$ plus $$9$$. To solve for $$p$$, we need to isolate $$p$$ on one side of the equation.

Substituting u = 1 into the Equation

To find the value of $$p$$ when $$u = 1$$, we need to substitute $$u = 1$$ into the equation $$p = u + 9$$. This involves replacing $$u$$ with $$1$$ in the equation.

p = 1 + 9

Solving for p

Now that we have substituted $$u = 1$$ into the equation, we can solve for $$p$$. To do this, we need to add $$1$$ and $$9$$ together.

p = 1 + 9

p = 10

Conclusion

In this article, we used the equation $$p = u + 9$$ to find the value of $$p$$ when $$u = 1$$. We substituted $$u = 1$$ into the equation and solved for $$p$$ by adding $$1$$ and $$9$$ together. The value of $$p$$ is $$10$$.

Understanding the Equation p = u + 9

The equation $$p = u + 9$$ is a simple linear equation that can be used to model a wide range of real-world situations. For example, if we were to use this equation to model the cost of a product, where $$p$$ is the total cost and $$u$$ is the cost of the product itself, then the constant $$9$$ would represent any additional costs, such as taxes or shipping.

Solving for p in Other Equations

The process of solving for $$p$$ in the equation $$p = u + 9$$ is similar to solving for $$p$$ in other equations. For example, if we had the equation $$p = 2u + 3$$, we would substitute the given value of $$u$$ into the equation and solve for $$p$$ by following the same steps.

Real-World Applications of the Equation p = u + 9

The equation $$p = u + 9$$ has a wide range of real-world applications. For example, in business, this equation can be used to calculate the total cost of a product, including any additional costs such as taxes or shipping. In science, this equation can be used to model the behavior of physical systems, such as the motion of an object under the influence of gravity.

Tips for Solving for p

When solving for $$p$$ in an equation, it is essential to follow the order of operations (PEMDAS) and to isolate $$p$$ on one side of the equation. Additionally, it is helpful to use variables and constants consistently throughout the equation, and to check the equation for any errors or inconsistencies.
