    Work: Find the solution of equation 100000/(6.9-x)/2-100000/6.9/2 = 1000-687.5 .
    Question type: Equation
    Solution:Original question:
     100000 ÷ (
69
10
 − x ) ÷ 2 − 100000 ÷
69
10
 ÷ 2 = 1000 −
1375

10
 − x )
     100000 ÷ 2 − 100000 ÷
69
10
 ÷ 2 × (

    Combine the items on the left of the equation:
     
1043125
138
 x =
8625
4

    The coefficient of the unknown number is reduced to 1 :
      x =

16690
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.285261
