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:
- \( 4x \)
- \( 7x \)
- \( -3 \)
- \( 1 \)
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:
- 4x and −3 - Not a pair of like terms.
- 7x and −3 - Not a pair of like terms.
- −3 and 1 - This is a pair of like terms.
- 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 \( 1 \).
