What do you obtain when you combine the terms in the expression 4x + 5 - x + 8?

• A. 3x + 13
• B. 4x + 13
• C. 5x + 13
• D. 3x + 5

Answer: (A)

To simplify the expression 4x + 5 - x + 8, you'll want to group the like terms together. First, identify the like terms in the expression. The terms containing the variable x are 4x and -x. When you combine these two terms, you perform the operation 4x - x, which equals 3x. Next, look at the constant terms, which are 5 and 8. When you combine these constants, you simply add them together: 5 + 8 equals 13. Putting it all together, after combining the like terms, you get 3x for the variable part and 13 for the constant part. Therefore, the simplified expression is 3x + 13, which corresponds with the answer you provided. This process of identifying and combining like terms is essential in algebra for simplifying expressions effectively.
