    The equation is transformed into :
     
251027
800
 +
7
200
 X = 4 X

    Transposition :
     
7
200
 X − 4 X = -
251027
800

    Combine the items on the left of the equation:
      -
793
200
 X = -
251027
800

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
251027
800
 =
793
200
 X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
793
200
 X =
251027
800

    The coefficient of the unknown number is reduced to 1 :
      X =
251027
800
 ÷
793
200
        =
251027

793

    We obtained :
      X =
251027
3172
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 79.138398
