[ 1/1 Equation]
    Work: Find the solution of equation X/0.09+(620.779-X)/0.13 = 5271.221 .
    Question type: Equation
    Solution:Original question:
      X ÷

100
 + (
620779
1000
 − X ) ÷
13
100
 =
5271221

    The equation is transformed into :
     
400
117
 X +
620779
130
 =
5271221
1000

    Transposition :
     
400
117
 X =
5271221
1000
 −
620779
130

    Combine the items on the right of the equation:
     
400
117
 X =
6447973
13000

    The coefficient of the unknown number is reduced to 1 :
      X =
6447973
13000
 ÷
400
117
        =
6447973
13000
 ×
117
400

    We obtained :
      X =
754412841
5200000
    This is the solution of the equation.

    By reducing fraction, we can get:
      X =
58031757
400000

    Convert the result to decimal form :
      X = 145.079393
