[ 1/1 Equation]
    Work: Find the solution of equation x3+21/100x+11/200 = 0 .
    Question type: Equation
    Solution:Original question:
      x × 3 + 21 ÷ 100 × x + 11 ÷ 200 = 0
     Left side of the equation = x × 3 +
21
100
 x +
11
200
                                             =

    The equation is transformed into :
     
321
100
 x +
11
200
 = 0

    Transposition :
     
321
100
 x = 0 −
11
200

    Combine the items on the right of the equation:
     
321
100
 x = -
