Equivalent equation

Which equation, when solved, results in a different value of x than the other three?

A.
78x34=20

Negative 7/8 x minus three-fourths = 20

B.
34+78x=20

Three-fourths + 7/8 x = negative 20

C.
718x3/4=20

Negative 7 ( 1/8 ) x minus three-fourths = 20

D.
78(87x)34=20(87)

Negative 7/8 (Negative 8/7 ) x minus three-fourths = 20 (Negative 8/7 )

Result

w = (Correct answer is: D) Wrong answer
