[ 1/1 Equation]
    Work: Find the solution of equation 200-（15%-X） = 100-（X-10%） .
    Question type: Equation
    Solution:Original question:
     200 − (
15
100
 − X ) = 100 − ( X −
10
100
)
    Remove the bracket on the left of the equation:
     Left side of the equation = 200 −
15
100
 + X
                                             =
3997
20
 + X
    The equation is transformed into :
     
3997
20
 + X = 100 − ( X −
10
100
)
    Remove the bracket on the right of the equation:
     Right side of the equation = 100 − X +
10
100
                                               =
1001
10
 − X
    The equation is transformed into :
     
3997
20
 + X =
1001
10
 − X

    Transposition :
      X + X =
1001
10
 −
3997
20

    Combine the items on the left of the equation:
     2 X =
1001
10
 −
3997
20

    Combine the items on the right of the equation:
     2 X = -
399
4

    The coefficient of the unknown number is reduced to 1 :
      X = -
399
4
 ÷ 2
        = -
399
4
 ×
1
2

    We obtained :
      X = -
399
8
    This is the solution of the equation.

    Convert the result to decimal form :
      X = - 49.875
