Question

Select all pairs of like terms in the expression 3x−4+x+7.(2 points)Responses−4 and 7−4 and 73x and −43x and −4x and −7x and −73x and x

Answer 1

In the expression \(3x - 4 + x + 7\), the like terms are those that have the same variable raised to the same power.

Let's break down the terms:
- \(3x\) and \(x\) are like terms because they both contain the variable \(x\).
- \(-4\) and \(7\) are constant terms and can also be considered like terms.

Based on this, the pairs of like terms in this expression are:
1. \(3x\) and \(x\)
2. \(-4\) and \(7\)

Therefore, the response that contains like terms is:
- **−4 and 7**
- **3x and x**

So, the pairs of like terms are:
- \(3x\) and \(x\)
- \(-4\) and \(7\)
