[ 1/1 Equation]
    Work: Find the solution of equation 20/135+X/87-(72-X)/1000 = 0.285 .
    Question type: Equation
    Solution:Original question:
     20 ÷ 135 + X ÷ 87 − (72 − X ) ÷ 1000 =
57
200
     Left side of the equation =
4
27
 + X ×

    Combine the items on the right of the equation:
     
1087
87000
 X =
5639
27000

    The coefficient of the unknown number is reduced to 1 :
      X =
5639
27000
 ÷
1087
87000
        =
5639
27000

    We obtained :
      X =
163531
9783
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 16.715834
