    The equation is transformed into :
     
35861
1000
 +
1
250
 X = 4 X

    Transposition :
     
1
250
 X − 4 X = -
35861
1000

    Combine the items on the left of the equation:
      -
999
250
 X = -
35861
1000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
35861
1000
 =
999
250
 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 :
     
999
250
 X =
35861
1000

    The coefficient of the unknown number is reduced to 1 :
      X =
35861
1000
 ÷
999
250
        =
35861
1000
 ×
250
999
        =

4
 ×
1
999

    We obtained :
      X =
35861
3996
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 8.974224
