[ 1/1 Equation]
    Work: Find the solution of equation 1/10*(x-(200+1/10*(x-200)+300))+300 = 200+1/10*(x-200) .
    Question type: Equation
    Solution:Original question:
     1 ÷ 10 × ( x − (200 + 1 ÷ 10 × ( x − 200) + 300)) + 300 = 200 + 1 ÷ 10 × ( x − 200)
     Left side of the equation =
1
10
( x − (200 + 1 ÷ 10 × ( x − 200) + 300)) + 300
    The equation is transformed into :
     
1
10
( x − (200 + 1 ÷ 10 × ( x − 200) + 300)) + 300 = 200 + 1 ÷ 10 × ( x − 200)

    The equation is transformed into :

 x + 252 = 200 + 1 ÷ 10 × ( x − 200)
     Right side of the equation = 200 +

 x = 180 − 252

    Combine the items on the left of the equation:
      -
1
100
 x = 180 − 252

    Combine the items on the right of the equation:
      -
1
100
 x = - 72

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     72 =
1
100
 x

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
1
100
 x = 72

    The coefficient of the unknown number is reduced to 1 :
      x = 72 ÷
1
100
        = 72 × 100

    We obtained :
      x = 7200
    This is the solution of the equation.
