Simplify 3m + 2 - m + 4.

• A. 2m + 6
• B. 3m + 6
• C. 4m + 2
• D. 4m + 6

Answer: (A)

To simplify the expression (3m + 2 - m + 4), start by identifying and combining like terms.

In this expression, the terms involving (m) are (3m) and (-m). When you combine these, you perform the operation:

[

3m - m = 2m.

]

Next, look at the constant terms (2) and (4). Combining these gives:

[

2 + 4 = 6.

]

Putting it all together, the simplified expression becomes:

[

2m + 6.

]

This matches the option provided, confirming that this is indeed the correct answer. This process of identifying like terms—those that have the same variable part—and combining them is crucial in algebra to arrive at a simplified expression. Understanding how to perform these operations will greatly assist you in further simplifying algebraic expressions in your studies.
