Equivalent equation

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


Negative 7/8 x minus three-fourths = 20


Three-fourths + 7/8 x = negative 20


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


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


w = (Correct answer is: D) Wrong answer
