[ 1/1 Equation]
    Work: Find the solution of equation [（X+3900）/3900]*0.397 = 5.4 .
    Question type: Equation
    Solution:Original question:
     (( X + 3900) ÷ 3900) ×
397
1000
 =
27
5
    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
 =
27
5

    Transposition :
     
397
3900000
 X =
27
5
 −
397
1000

    Combine the items on the right of the equation:
     
397
3900000
 X =
5003
1000

    The coefficient of the unknown number is reduced to 1 :
      X =
5003
1000
 ÷
397
3900000
        =
5003
1000
 ×
3900000
397
        = 5003 ×
3900
397

    We obtained :
      X =
19511700
397
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 49147.858942
