[ 1/1 Equation]
    Work: Find the solution of equation (X*0.13+X)*0.09+(X*0.13+X) = 280 .
    Question type: Equation
    Solution:Original question:
     ( X ×
13
100
 + X ) ×
9
100
 + ( X ×
13
100
 + X ) = 280
    Remove the bracket on the left of the equation:
     Left side of the equation = X ×

 X + ( X ×
13
100
 + X )
                                             =
1017
10000
 X + X ×
13
100
 + X
                                             =
12317
10000
 X
    The equation is transformed into :
     
12317
10000
 X = 280

    The coefficient of the unknown number is reduced to 1 :
      X = 280 ÷
12317
10000
        = 280 ×
10000
12317

    We obtained :
      X =
2800000
12317
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 227.328083
