    The equation is transformed into :
     
423
40000
x
74379
140000
=

100

    Transposition :
     
423
40000
x =
7
100
+
74379
140000

    Combine the items on the right of the equation:
     
423
40000
x =
84179
140000

    The coefficient of the unknown number is reduced to 1 :
      x =
84179
140000
÷
423
40000
        =
84179
140000

    We obtained :
      x =
168358
2961
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 56.858494
