In the expression \( 4x - 3 + 7x + 1 \), we can identify the like terms. Like terms are terms that have the same variable raised to the same power.

The terms in the expression are:

  1. \( 4x \)
  2. \( 7x \)
  3. \( -3 \)
  4. \( 1 \)

The pairs of like terms are:

  • \( 4x \) and \( 7x \) (both have the variable \( x \))
  • \( -3 \) and \( 1 \) (both are constant terms)

Now, let's check the given responses for like term pairs:

  1. 4x and −3 - Not a pair of like terms.
  2. 7x and −3 - Not a pair of like terms.
  3. −3 and 1 - This is a pair of like terms.
  4. 4x and 7x - This is a pair of like terms.

So the correct pairs of like terms from the expression \( 4x - 3 + 7x + 1 \) are \( 4x \) and \( 7x \), and \( -3 \) and \( 1 \).
