Answer:

B C and E

Step-by-step explanation:

A is not. -4x/1 is not the same as -1*x/4

B works. The minus sign is taken outside the brackets and 1/4 is put in the brackets. Nothing illegal has been done.

C works. 3 and -x have been put over a common denominator.

D wrong. Were did the minus sign go?

E works
