[ 1/1 Equation]
    Work: Find the solution of equation 4200x×(1+5%)+84000+[x×4200-(1-93%)]×20% = 320000 .
    Question type: Equation
    Solution:Original question:
     4200 x (1 +

100
) + 84000 + ( x × 4200 − (1 −
93
100
)) ×

 = 320000
    Remove the bracket on the left of the equation:
     Left side of the equation = 4200 x × 1 + 4200 x ×

    The equation is transformed into :
     5250 x +
41999993
500
 = 320000

    Transposition :
     5250 x = 320000 −
41999993
500

    Combine the items on the right of the equation:
     5250 x =
118000007
500

    The coefficient of the unknown number is reduced to 1 :
      x =
118000007
500
 ÷ 5250
        =
118000007
500
 ×
1
5250

    We obtained :
      x =
118000007
2625000
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 44.952384
