[ 1/1 Equation]
    Work: Find the solution of equation (200+x-20)(60-0.1) = 14000 .
    Question type: Equation
    Solution:Original question:
     (200 + x − 20)(60 −
1
10
) = 14000
    Remove the bracket on the left of the equation:
     Left side of the equation = 200(60 −

                                             = 11980 +
599
10
 x − 1200 + 2
                                             = 10782 +
599
10
 x
    The equation is transformed into :
     10782 +
599
10
 x = 14000

    Transposition :
     
599
10
 x = 14000 − 10782

    Combine the items on the right of the equation:
     
599
10
 x = 3218

    The coefficient of the unknown number is reduced to 1 :
      x = 3218 ÷
599
10
        = 3218 ×
10
599

    We obtained :
      x =
32180
599
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 53.722871
