    The equation is transformed into :
     30 =
25981
500
 +
229
1000
 x

    Transposition :
      -
229
1000
 x =
25981
500
 − 30

    Combine the items on the right of the equation:
      -
229
1000
 x =
10981
500

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      -
10981
500
 =
229
1000
 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 :
     
229
1000
 x = -
10981
500

    The coefficient of the unknown number is reduced to 1 :
      x = -
10981
500
 ÷
229
1000
        = -
10981

    We obtained :
      x = -
21962
229
    This is the solution of the equation.

    Convert the result to decimal form :
      x = - 95.90393
