x and −7

Answer 1

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

1. Like terms with \(x\):

   • \(3x\) and \(x\)

2. Like constant terms:

   • \(-4\) and \(7\) (though these are constants and not like terms in the variable sense)

Therefore, the pairs of like terms in the expression are:

• \(3x\) and \(x\)

The correct response is:

• 3x and x
