[ 1/1 Equation]
    Work: Find the solution of equation 0.8x+0.13(3x+500)+0.07(9x+3500) = 2500 .
    Question type: Equation
    Solution:Original question:

100
 x + 245
                                             =
91
50
 x + 310
    The equation is transformed into :
     
91
50
 x + 310 = 2500

    Transposition :
     
91
50
 x = 2500 − 310

    Combine the items on the right of the equation:
     
91
50
 x = 2190

    The coefficient of the unknown number is reduced to 1 :
      x = 2190 ÷
91
50
        = 2190 ×
50
91

    We obtained :
      x =
109500
91
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1203.296703
