[ 1/1 Equation]
    Work: Find the solution of equation 20/135+X/87-(92-X)/1000 = 0.285 .
    Question type: Equation
    Solution:Original question:
     20 ÷ 135 + X ÷ 87 − (92 − X ) ÷ 1000 =
57
200
     Left side of the equation =
4
27
 + X ×

 −
379
6750

    Combine the items on the right of the equation:
     
1087
87000
 X =
6179
27000

    The coefficient of the unknown number is reduced to 1 :
      X =
6179
27000
 ÷
1087
87000
        =
6179
27000

    We obtained :
      X =
179191
9783
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 18.31657
