To identify the pairs of like terms in the expression \(2x - 6 + 5x + 3\), we'll first group the terms:

  1. Like terms involving \(x\):

    • \(2x\) and \(5x\) are both like terms (both are \(x\) terms).
  2. Constant terms:

    • \(-6\) and \(3\) are like terms (both are constant terms).

Now, let's analyze the provided responses:

  1. 3x and 3: Not applicable, since we don't have \(3x\) in the expression.
  2. 2x and 5x: Correct, they are like terms.
  3. 2x and -6: Not like terms; one is an \(x\) term and the other is a constant.
  4. −6 and 3: Correct, they are like terms.

Therefore, the pairs of like terms are:

  • \(2x\) and \(5x\)
  • \(-6\) and \(3\)

So the correct responses are:

  • 2x and 5x
  • −6 and 3
