Breaking Down the Expression

The expression "4n 9 2 5 2n" is a combination of numbers and variables. The variable in this expression is "n," which represents an unknown value. The numbers in the expression are constants that do not change. The expression has four constants, which are "4," "9," "2," and "5." The constants are separated by spaces and are not related to the variable "n."

Understanding the Expression

To understand the expression "4n 9 2 5 2n," you need to look at it as a whole. The expression is an algebraic expression that can be simplified and evaluated. When you simplify the expression, you can see that it has two terms, "4n" and "2n," which are like terms. The constants "9" and "5" are not related to the variable "n" and are called the constant terms.

Solving the Expression

To solve the expression "4n 9 2 5 2n," you need to simplify it first. Start by combining the like terms, which are "4n" and "2n." When you combine them, you get "6n." Therefore, the expression becomes "6n 9 5." You can simplify further by adding the constant terms, which are "9" and "5." When you add them, you get "14." Therefore, the simplified expression is "6n 14."

Checking Your Answer

To check your answer, you can substitute a value for "n" and evaluate the expression. For example, if you substitute "2" for "n," you get "6(2) 14," which simplifies to "12 14" or "26." Therefore, the value of the expression when "n" is equal to "2" is "26."

Conclusion

In conclusion, the expression "4n 9 2 5 2n" is an algebraic expression that can be simplified and evaluated. To simplify the expression, you need to combine the like terms and add the constant terms. Once you have simplified the expression, you can substitute a value for "n" to evaluate it. As a teacher, it is essential to break down complicated mathematical concepts into simpler terms that students can understand. By following the steps outlined in this article, you can teach your students how to solve the expression "4n 9 2 5 2n."
