[ 1/1 Equation]
    Work: Find the solution of equation x*3-10x*2-17x+20 = 0 .
    Question type: Equation
    Solution:Original question:
      x × 310 x × 217 x + 20 = 0
     Left side of the equation = x × 320 x 17 x + 20
                                             = - 34 x + 20
    The equation is transformed into :
      - 34 x + 20 = 0

    Transposition :
      - 34 x = 020

    Combine the items on the right of the equation:
      - 34 x = - 20

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     20 = 34 x

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     34 x = 20

    The coefficient of the unknown number is reduced to 1 :
      x = 20 ÷ 34
        = 20 ×
1
34
        = 10 ×
1
17

    We obtained :
      x =
10
17
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.588235
