[ 1/1 Equation]
    Work: Find the solution of equation Y×0.3÷3%-(Y×0.3÷3%)*60%-489 = 0 .
    Question type: Equation
    Solution:Original question:

489
                                             = 10 Y Y × 6489
                                             = 4 Y 489
    The equation is transformed into :
     4 Y 489 = 0

    Transposition :
     4 Y = 0 + 489

    Combine the items on the right of the equation:
     4 Y = 489

    The coefficient of the unknown number is reduced to 1 :
      Y = 489 ÷ 4
        = 489 ×

4

    We obtained :
      Y =
489
4
    This is the solution of the equation.

    Convert the result to decimal form :
      Y = 122.25
