−3x+7y
negative 3 x plus 7 y

7y−3x
7 y minus 3 x

−7y+3x
negative 7 y plus 3 x

−7y−3x

Answer 1

To determine which two expressions are equivalent, let's examine each option.

1. **−3x + 7y**
2. **7y − 3x**: This can be rewritten as 7y + (-3x), which is the same as the first expression since the order of addition does not change the sum.
3. **−7y + 3x**: This is the negative of both terms, hence not equivalent to the first two.
4. **−7y − 3x**: This is also different, as both terms are negated.

The two equivalent expressions are:

- **−3x + 7y**
- **7y − 3x**

These two expressions represent the same relationship.
