[ 1/1 Equation]
    Work: Find the solution of equation 100/(1.065+x)+100/(1.055+x) = 88.58*1.06*2 .
    Question type: Equation
    Solution:Original question:
     100 ÷ (
213
200
 + x ) + 100 ÷ (
211
200
 + x ) =
4429
50
 ×
53
50
 × 2
     Multiply both sides of the equation by:(
213
200
 + x )
     100 + 100 ÷ (
211
200
 + x ) × (
213
200
 + x ) =
4429

 + x )
    Remove a bracket on the left of the equation:：
     100 + 100 ÷ (
211
200
 + x ) ×
213
200
 + 100 ÷ (
211
200
 + x ) × x =
4429
50
 ×
53
50
 × 2(
213
200
 + x )
    Remove a bracket on the right of the equation:：
     100 + 100 ÷ (
211
200
 + x ) ×
213
200
 + 100 ÷ (
211

    The equation is reduced to :
     100 +
213
2
 ÷ (
211
200
 + x ) + 100 ÷ (
211
200
 + x ) × x =
49998981
250000
 +
234737
1250
 x
     Multiply both sides of the equation by:(
211
200
 + x )
     100(
211
200
 + x ) +
213
2
 + 100 x =
49998981
250000
(
211
200
 + x ) +
234737

    Remove a bracket on the left of the equation:
     100 ×
211
200
 + 100 x +
213
2
 + 100 x =

 x (
211
200
 + x )
    Remove a bracket on the right of the equation:：
     100 ×
211
200
 + 100 x +
213
2
 + 100 x =
