 +
1307
100
 x = (75 + x ) ×
399
50
     Left side of the equation = 585 +
1307
100
 x
    The equation is transformed into :
     585 +
1307
100
 x = (75 + x ) ×
399
50
    Remove the bracket on the right of the equation:
     Right side of the equation = 75 ×
399
50
 + x ×
399

 − 585

    Combine the items on the left of the equation:
     
509
100
 x =
1197
2
 − 585

    Combine the items on the right of the equation:
     
509
100
 x =
27
2

    The coefficient of the unknown number is reduced to 1 :
      x =
27

509
        = 27 ×
50
509

    We obtained :
      x =
1350
509
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 2.652259
