    The equation is transformed into :
     
10239
50
 Q −
76593
250
 = 0

    Transposition :
     
10239
50
 Q = 0 +
76593
250

    Combine the items on the right of the equation:
     
10239
50
 Q =
76593
250

    The coefficient of the unknown number is reduced to 1 :
      Q =
76593
250
 ÷
10239

    We obtained :
      Q =
25531
17065
    This is the solution of the equation.

    Convert the result to decimal form :
      Q = 1.496103
