Simplifying the Expression (2x + 5) + (x + 4)
In mathematics, simplifying expressions is a fundamental skill. This involves combining like terms to make the expression easier to understand and work with.
Let's break down the simplification of the expression (2x + 5) + (x + 4):
Step 1: Identify Like Terms
- Like terms are terms that have the same variable and exponent. In our expression, we have:
- 2x and x (both have the variable 'x' raised to the power of 1)
- 5 and 4 (both are constants)
Step 2: Combine Like Terms
- Combine the 'x' terms: 2x + x = 3x
- Combine the constant terms: 5 + 4 = 9
Step 3: Write the Simplified Expression
After combining like terms, our simplified expression is 3x + 9.
Conclusion
By following these simple steps, we have successfully simplified the expression (2x + 5) + (x + 4) to 3x + 9. This simplified form is more concise and easier to work with in further calculations.
