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
