[ 1/1 Equation]
    Work: Find the solution of equation x+23+x*0.2+(x+x*0.2)*0.09 = 1670 .
    Question type: Equation
    Solution:Original question:
      x + 23 + x ×
1
5
 + ( x + x ×
1
5
) ×
9
100
 = 1670
     Left side of the equation =
6
5
 x + 23 + ( x + x ×
1
5
) ×
9
100
    The equation is transformed into :
     
6
5
 x + 23 + ( x + x ×
1
5
) ×
9
100
 = 1670
    Remove the bracket on the left of the equation:
     Left side of the equation =
6
5
 x + 23 + x ×

                                             =
327
250
 x + 23
    The equation is transformed into :
     
327
250
 x + 23 = 1670

    Transposition :
     
327
250
 x = 1670 − 23

    Combine the items on the right of the equation:
     
327
250
 x = 1647

    The coefficient of the unknown number is reduced to 1 :
      x = 1647 ÷
327
250
        = 1647 ×
250
327
        = 549 ×
250
109

    We obtained :
      x =
137250
109
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1259.174312
