[ 1/1 Equation]
    Work: Find the solution of equation y = 100-1997500/(3549+5040+19975) .
    Question type: Equation
    Solution:Original question:
      y = 100 − 1997500 ÷ (3549 + 5040 + 19975)
     Multiply both sides of the equation by:(3549 + 5040 + 19975)
      y (3549 + 5040 + 19975) = 100(3549 + 5040 + 19975) − 1997500
    Remove a bracket on the left of the equation:：
      y × 3549 + y × 5040 + y × 19975 = 100(3549 + 5040 + 19975) − 1997500
    Remove a bracket on the right of the equation:：
      y × 3549 + y × 5040 + y × 19975 = 100 × 3549 + 100 × 5040 + 100 × 19975 − 1997500
    The equation is reduced to :
      y × 3549 + y × 5040 + y × 19975 = 354900 + 504000 + 1997500 − 1997500
    The equation is reduced to :
     28564 y = 858900

    The coefficient of the unknown number is reduced to 1 :
      y = 858900 ÷ 28564
        = 858900 ×
1
28564
        = 214725 ×
1
7141

    We obtained :
      y =
214725
7141
    This is the solution of the equation.

    Convert the result to decimal form :
      y = 30.069318
