Introduction

In mathematics, simplifying expressions is a crucial step in solving equations and inequalities. The expression $$2(3+u)+7u$$ is a complex expression that requires several steps to simplify. In this article, we will analyze each step of the simplification process and provide the reason that justifies it.

Step 1: Distributive Property

The first step in simplifying the expression is to apply the distributive property. This property states that for any real numbers a, b, and c, the following equation holds:

a(b + c) = ab + ac

Using this property, we can rewrite the expression as:

2(3+u) = 6 + 2u

The reason for this step is to apply the distributive property, which allows us to multiply the term 2 by each term inside the parentheses.

Step 2: Combine Like Terms

The next step is to combine like terms. Like terms are terms that have the same variable raised to the same power. In this case, we have two terms with the variable u:

6 + 2u + 7u

We can combine these two terms by adding their coefficients:

6 + 9u

The reason for this step is to combine like terms, which simplifies the expression and makes it easier to work with.

Step 3: Final Simplification

The final step is to simplify the expression by combining the constant term with the variable term:

6 + 9u

This is the final simplified form of the expression.

Conclusion

In conclusion, the expression $$2(3+u)+7u$$ is simplified in several steps. Each step is justified by the application of mathematical properties and rules. The distributive property is used to rewrite the expression, and like terms are combined to simplify the expression further. The final simplified form of the expression is $$6 + 9u$$.
