Answer 1

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

The pairs of terms from the expression are:
- \(3x\) and \(x\) (both are terms involving \(x\))
- \(-4\) and \(7\) (both are constant terms)

So the like term pairs are:
- \(3x\) and \(x\)
- \(-4\) and \(7\)

The correct response is:
- **3x and x**
- **−4 and 7**
