[ 1/1 Equation]
    Work: Find the solution of equation X-（x*0.1）-（X*0.2）-7 = 898 .
    Question type: Equation
    Solution:Original question:
      X − ( X ×
1
10
) − ( X ×
1
5
) − 7 = 898
    Remove the bracket on the left of the equation:
     Left side of the equation = X − X ×

) − 7
                                             =

 X − 7
    The equation is transformed into :
     
7
10
 X − 7 = 898

    Transposition :
     
7
10
 X = 898 + 7

    Combine the items on the right of the equation:
     
7
10
 X = 905

    The coefficient of the unknown number is reduced to 1 :
      X = 905 ÷
7
10
        = 905 ×
10
7

    We obtained :
      X =
9050
7
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 1292.857143
