[ 1/1 Equation]
    Work: Find the solution of equation X+4+19+20%X+(X+20%X)*9% = 1670 .
    Question type: Equation
    Solution:Original question:
      X + 4 + 19 +
20
100
 X + ( X +
20
100
 X ) ×

 = 1670
     Left side of the equation =

    The equation is transformed into :
     
6
5
 X + 23 + ( X +
20
100
 X ) ×
9
100
 = 1670
    Remove the bracket on the left of the equation:
     Left side of the equation =

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
