What Is The Result When You Combine Only The Constants In The Following Expression?$\[ 3a - 6b + 3 - 7a + 10 \\]
Introduction
In algebra, combining like terms is a fundamental concept that helps simplify expressions and make them easier to work with. When we combine like terms, we are essentially adding or subtracting the coefficients of the same variables. However, when we are only interested in combining the constants in an expression, we need to follow a specific set of rules. In this article, we will explore the result of combining only the constants in a given expression.
Understanding Constants
Constants are numbers that do not have any variables associated with them. In the given expression, the constants are the numbers 3, -6, 3, and 10. These numbers are not associated with any variables, such as a or b.
The Given Expression
The given expression is:
To combine only the constants in this expression, we need to identify the constants and then add or subtract them as necessary.
Combining the Constants
The constants in the given expression are 3, -6, 3, and 10. To combine these constants, we need to follow the order of operations (PEMDAS):
- Parentheses: None
- Exponents: None
- Multiplication and Division: None
- Addition and Subtraction: Combine the constants
The constants can be combined as follows:
Simplifying the Constants
Now that we have combined the constants, we can simplify the expression by adding and subtracting the numbers:
Therefore, the result of combining only the constants in the given expression is 10.
Conclusion
In conclusion, combining only the constants in an expression involves identifying the constants and then adding or subtracting them as necessary. By following the order of operations and simplifying the expression, we can arrive at the final result. In this article, we explored the result of combining only the constants in a given expression and found that the result is 10.
