[ 1/1 Equation]
    Work: Find the solution of equation (20—x)/(20.088—x) = (20+x)/(20.039+x) .
    Question type: Equation
    Solution:Original question:
     (20 x ) ÷ (
2511
125
x ) = (20 + x ) ÷ (
20039
1000
+ x )
     Multiply both sides of the equation by:(
2511
125
x ) ,  (
20039
1000
+ x )
     (20 x )(
20039
1000
+ x ) = (20 + x )(
2511
125
x )
    Remove a bracket on the left of the equation::
     20(
20039
1000
+ x ) x (
20039
1000
+ x ) = (20 + x )(
2511
125
x )
    Remove a bracket on the right of the equation::
     20(
20039
1000
+ x ) x (
20039
1000
+ x ) = 20(
2511
125
x ) + x (
2511
125
x )
    Remove a bracket on the left of the equation:
     20 ×
20039
1000
+ 20 x x (
20039
1000
+ x ) = 20(
2511
125
x ) + x (
2511
125
x )
    Remove a bracket on the right of the equation::
     20 ×
20039
1000
+ 20 x x (
20039
1000
+ x ) = 20 ×
2511
125
20 x + x (
2511
125
x )
    The equation is reduced to :
     
20039
50
+ 20 x x (
20039
1000
+ x ) =
10044
25
20 x + x (
2511
125
x )
    Remove a bracket on the left of the equation:
     
20039

+ 20 x x ×
20039
1000
x x =
10044
25
20 x + x (

+ 20 x x ×
20039
1000
x x =
10044
25
20 x + x ×
