    The equation is reduced to :
     48600 − 42 X (
49
1000

 X
    Remove a bracket on the left of the equation:
     48600 − 42 X ×
49
1000
 − 42 X ×

 X
    The equation is reduced to :
     48600 −
1029
500
 X −

1000
 X
    The equation is reduced to :
     48600 −
1449
500
 X =
1197
1000
 X

    Transposition :
      -
1449
500
 X −
1197
1000
 X = - 48600

    Combine the items on the left of the equation:
      -
819
200
 X = - 48600

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     48600 =
819
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 :
     
819
200
 X = 48600

    The coefficient of the unknown number is reduced to 1 :
      X = 48600 ÷
819
200
        = 48600 ×
200
819
        = 5400 ×
200
91

    We obtained :
      X =
1080000
91
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 11868.131868
