[ 1/1 Equation]
    Work: Find the solution of equation 1247000*x*0.1+（200-x）*1238000*0.1 = 42587200 .
    Question type: Equation
    Solution:Original question:
     1247000 x ×
1
10
 + (200 − x ) × 1238000 ×
1
10
 = 42587200
     Left side of the equation = 124700 x + (200 − x ) × 123800
    The equation is transformed into :
     124700 x + (200 − x ) × 123800 = 42587200
    Remove the bracket on the left of the equation:
     Left side of the equation = 124700 x + 200 × 123800 − x × 123800
                                             = 124700 x + 24760000 − x × 123800
                                             = 900 x + 24760000
    The equation is transformed into :
     900 x + 24760000 = 42587200

    Transposition :
     900 x = 42587200 − 24760000

    Combine the items on the right of the equation:
     900 x = 17827200

    The coefficient of the unknown number is reduced to 1 :
      x = 17827200 ÷ 900
        = 17827200 ×
1
900
        = 19808 × 1

    We obtained :
      x = 19808
    This is the solution of the equation.
