Question

All of the following expressions are equivalent except _____.

-4 - y
-4 + y
- y - 4
- y + (-4)

Answer 1

All of the following expressions are equivalent except -4 + y... the first option will get you a negative number, the third and forth option will also get you a negative. So therefore, the second option is the best answer because it gets you a positive number unlike the other three.

Answer 2

if what I stated above does not make sense you can try plugging in a value for y and try solving the problems.

Answer 3

I really hope this helped! :))
