    The equation is transformed into :
     
230
63
 +
155
63
 x = 400

    Transposition :
     
155
63
 x = 400 −
230
63

    Combine the items on the right of the equation:
     
155
63
 x =
24970
63

    The coefficient of the unknown number is reduced to 1 :
      x =
24970
63
 ÷
155
63
        =

    We obtained :
      x =
4994
31
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 161.096774
