Which equation has infinitely many solutions?

A. 1-2x=2 (1-x)

B. 2x=1-2x

C. 2x = - 1/2x

D. 1-2x = - (2x-1)

1-2x = - (2x-1) is the equation that has infinitely many solutions because - (2x-1) can be simplified using the distributive property as - 2x+1 which is the same as 1-2x but just the order switched.
