To determine which two expressions are equivalent, we can analyze the provided options:
-
−3x + 7y: This can be expressed as \( 7y - 3x \) by rearranging the terms.
-
−7y + 3x: This is not equivalent to \( −3x + 7y \).
-
−7y − 3x: This is clearly not equivalent to \( −3x + 7y \) as it has different signs and different coefficients.
-
7y − 3x: This is equivalent to \( −3x + 7y \) since rearranging \( −3x + 7y \) gives us \( 7y - 3x \).
Thus, the two equivalent expressions are:
- −3x + 7y
- 7y − 3x
