11/12x - 1/4 =8
lets cross multiply ....
i.e, 11 X 4 - (12x) X 1 =8 (now this is the equation we need to solve to get x)
    => 44-12x = 8
    => -12x = 8-44 
    =>  -12x = -36
    => x = -36/-12 = 3...
therefore x = 3 ...
 
 you can also verify your answer.....by putting 3 in x 's place ....
i.e, 11X4 - 12 X 3 X1 =8
      44 - 36 = 8
      8=8
i.e, LHS=RHS ......

Hope it helps !!!
