What is the answer -3=-x

A. x=3
B. x=-3

x=3 because you divide both sides by a negative which gives you a positive

haha the answer is A. divide both sides by -1....also plug in 3 and it works...plug in -3 and it becomes positive 3

Divide both sides by -1 to get:

-3/-1 = -x/-1
3 = x

x=3
if you put x= -3, then it would be like this -3= -1(-3), making the 3 on the right positive.

answer is A. x=3
the reason we cancel both side negative..simple math i guess

x=3
