Answer 1

In the expression \(3x - 4 + x + 7\), we can identify the like terms. Like terms are terms that contain the same variable raised to the same power.

1. The terms \(3x\) and \(x\) are like terms because they both contain the variable \(x\).
2. The terms \(-4\) and \(7\) are like terms because they are both constant terms without any variables.

So the pairs of like terms are:

• \(3x\) and \(x\)
• \(-4\) and \(7\)

The correct responses would be:

• \(3x\) and \(x\)
• \(-4\) and \(7\)
