[ 1/1 Equation]
    Work: Find the solution of equation [（X+3900）/3900]*0.397 = 13 .
    Question type: Equation
    Solution:Original question:
     (( X + 3900) ÷ 3900) ×
397
1000
 = 13
    Remove the bracket on the left of the equation:
     Left side of the equation = ( X + 3900) ÷ 3900 ×
397
1000
                                             = ( X + 3900) ×
397
3900000
                                             = X ×
397
3900000
 + 3900 ×
397
3900000
                                             = X ×
397
3900000
 +
397
1000
    The equation is transformed into :
     
397
3900000
 X +
397
1000
 = 13

    Transposition :
     
397
3900000
 X = 13 −
397
1000

    Combine the items on the right of the equation:
     
397
3900000
 X =
12603
1000

    The coefficient of the unknown number is reduced to 1 :
      X =
12603
1000
 ÷
397
3900000
        =
12603
1000
 ×
3900000
397
        = 12603 ×
3900
397

    We obtained :
      X =
49151700
397
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 123807.808564
