What is the result of combining -2x + 4x - 3 + 5?

• A. 2x + 2
• B. 2x + 3
• C. -3x + 2
• D. -2x + 5

Answer: (A)

To find the result of combining the terms in the expression -2x + 4x - 3 + 5, we start by identifying and grouping the like terms. The first step is to look at the terms involving the variable x. We have -2x and 4x. When we combine these, we perform the operation: -2x + 4x = (4 - 2)x = 2x. Next, we focus on the constant terms, which are -3 and +5. We combine these as follows: -3 + 5 = 2. Now we can combine our results. The combined expression from the x terms is 2x, and from the constant terms, we have +2. Therefore, when we bring these results together, we have: 2x + 2. This matches the first choice provided, demonstrating that it is indeed the correct answer. The process of identifying and summing like terms yields a simplified expression, allowing us to present the result in a clear and concise manner.
