Understanding the Problem

In this article, we will focus on simplifying a given algebraic expression by combining like terms and applying mathematical properties. The expression we will be working with is $21h - 10h + 16 - 9 + 14h + 5$ . Our goal is to rewrite this expression in a simpler form by combining like terms and applying mathematical properties.

Step 1: Apply the Commutative Property

The commutative property states that the order of the terms in an expression does not change the value of the expression. We can use this property to rearrange the terms in the given expression.

21h - 10h + 16 - 9 + 14h + 5 = 21h - 10h + 14h + 16 - 9 + 5

Step 2: Combine Like Terms

Like terms are terms that have the same variable raised to the same power. In this case, we have three like terms: $21h$ , $-10h$ , and $14h$ . We can combine these terms by adding their coefficients.

21h - 10h + 14h = (21 - 10 + 14)h = 25h

Step 3: Simplify the Constant Terms

The constant terms in the expression are $16$ , $-9$ , and $5$ . We can simplify these terms by adding them together.

16 - 9 + 5 = 12

Step 4: Combine the Simplified Terms

Now that we have simplified the like terms and the constant terms, we can combine them to get the final simplified expression.

25h + 12

Conclusion

In this article, we have simplified the given algebraic expression by combining like terms and applying mathematical properties. We have shown that the expression $21h - 10h + 16 - 9 + 14h + 5$ is equivalent to $25h + 12$ . This simplified expression is easier to work with and can be used in a variety of mathematical applications.

Final Answer

The final answer is $\boxed{25h + 12}$ .
