[ 1/1 Equation]
    Work: Find the solution of equation x+80+0.2x+（1.2x）*13% = 2000 .
    Question type: Equation
    Solution:Original question:
      x + 80 +
1
5
 x + (
6
5
 x ) ×
13
100
 = 2000
     Left side of the equation =
6
5
 x + 80 + (
6
5
 x ) ×
13
100
    The equation is transformed into :
     
6
5
 x + 80 + (
6
5
 x ) ×
13
100
 = 2000
    Remove the bracket on the left of the equation:
     Left side of the equation =
6
5
 x + 80 +
6
5
 x ×

 x
                                             =
339
250
 x + 80
    The equation is transformed into :
     
339
250
 x + 80 = 2000

    Transposition :
     
339
250
 x = 2000 − 80

    Combine the items on the right of the equation:
     
339
250
 x = 1920

    The coefficient of the unknown number is reduced to 1 :
      x = 1920 ÷
339
250
        = 1920 ×
250
339
        = 640 ×
250
113

    We obtained :
      x =
160000
113
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1415.929204
