[ 1/1 Equation]
    Work: Find the solution of equation (0.4+x)×x÷(0.4-x) = 0.0102 .
    Question type: Equation
    Solution:Original question:
     (
2
5
+ x ) x ÷ (
2
5
x ) =
51
5000
     Multiply both sides of the equation by:(
2
5
x )
     (
2
5
+ x ) x =
51
5000
(
2
5
x )
    Remove a bracket on the left of the equation::
     
2
5
x + x x =
51
5000
(
