[ 1/1 Equation]
    Work: Find the solution of equation 0.358*100+0.794*X = （100+X）*0.405 .
    Question type: Equation
    Solution:Original question:
     
179
500
 × 100 +
397
500
 X = (100 + X ) ×
81
200
     Left side of the equation =
179
5
 +
397
500
 X
    The equation is transformed into :
     
179
5
 +
397
500
 X = (100 + X ) ×
81
200
    Remove the bracket on the right of the equation:
     Right side of the equation = 100 ×
81
200
 + X ×
81
200
                                               =
81
2
 + X ×
81

    Combine the items on the left of the equation:
     
389
1000
 X =
81
2
 −
179
5

    Combine the items on the right of the equation:
     
389
1000
 X =
47
10

    The coefficient of the unknown number is reduced to 1 :
      X =
47
10
 ÷
389
1000
        =
47

 ×
1000
389
        = 47 ×
100
389

    We obtained :
      X =
4700
389
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 12.082262
