option A i.e. Three-fourths (four-thirds) x = negative 6 (four-thirds).
<u>Step-by-step explanation:</u>
We have , The given expression as Three-fourths x = negative 6  , which can be written as  . Now in order to solve this equation in one step , we must notice that coefficient of x must be 1 but it's
 . Now in order to solve this equation in one step , we must notice that coefficient of x must be 1 but it's   , Let's make coefficient of x  as 1 by multiplying both side of equations by 4/3:
 , Let's make coefficient of x  as 1 by multiplying both side of equations by 4/3:
