Answer:
-3mn
Step-by-step explanation:
It seems you might be missing some of the question, as you haven't given what m and n are equal to.
If the question has just given you x, then you would simply just simplify it to get -3mn.
A - B - C =
-3 - 4 + 5 =
-7 + 5 =
-2
negative three minus four plus five is negative two
