    Combine the items on the left of the equation:
      -
977000
45096269
 y = -
2075300
20753
 +
191
2

    Combine the items on the right of the equation:
      -
977000
45096269
 y = -
186777
41506

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
186777
41506
 =
977000
45096269
 y

    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 :
     
977000
45096269
 y =
186777
41506

    The coefficient of the unknown number is reduced to 1 :
      y =
186777
41506
 ÷
977000
45096269
        =
186777
41506
 ×
45096269
977000

    We obtained :
      y =
8422945835013
40551362000
    This is the solution of the equation.
