[ 1/1 Equation]
    Work: Find the solution of equation x（1+18%）（1+5%）+38+27.8 = 827.28 .
    Question type: Equation
    Solution:Original question:
      x (1 +
18
100
)(1 +
5
100
) + 38 +
139

     Left side of the equation = x (1 +
18
100
)(1 +

    The equation is transformed into :
      x (1 +
18
100
)(1 +

    The equation is transformed into :
     
1239
1000
 x +
329
5
 =
20682
25

    Transposition :
     
1239
1000
 x =
20682
25
 −
329
5

    Combine the items on the right of the equation:
     
1239
1000
 x =
19037
25

    The coefficient of the unknown number is reduced to 1 :
      x =
19037
25
 ÷
1239
1000
        =
19037
25
 ×
1000
1239
        = 19037 ×
40
1239

    We obtained :
      x =
761480
1239
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 614.592413
