    Work: Find the solution of equation （6.66+x）/（6.66-x）*（15+6.09+x）/（0.03+x/222） = 20000 .
    Question type: Equation
    Solution:Original question:
     (

 + x ) ÷ (
333
50
 − x ) × (15 +
609
100
 + x ) ÷ (
3
100
 + x ÷ 222) = 20000
     Multiply both sides of the equation by:(

 − x )
     (
333
50
 + x )(15 +
609
100
