    Work: Find the solution of equation （12000+x+3000+180）*0.13+12000+x+3180 = 18740 .
    Question type: Equation
    Solution:Original question:
     (12000 + x + 3000 + 180) ×
13
100
 + 12000 + x + 3180 = 18740
     Left side of the equation = (12000 + x + 3000 + 180) ×
13
100
 + 15180 + x
    The equation is transformed into :
     (12000 + x + 3000 + 180) ×
13
100
 + 15180 + x = 18740
    Remove the bracket on the left of the equation:
     Left side of the equation = 12000 ×

100
 x = 18740

    Transposition :
     
113
100
 x = 18740 −
85767
5

    Combine the items on the right of the equation:
     
113
100
 x =
7933
5

    The coefficient of the unknown number is reduced to 1 :
      x =
7933
5
 ÷
113
100
        =
7933
5
 ×
100
113
        = 7933 ×
20
113

    We obtained :
      x =
158660
113
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1404.070796
