[ 1/1 Equation]
    Work: Find the solution of equation (231+x)*49.9 = 231*51+20x .
    Question type: Equation
    Solution:Original question:
     (231 + x ) ×
499
10
 = 231 × 51 + 20 x
    Remove the bracket on the left of the equation:
     Left side of the equation = 231 ×
499
10
 + x ×
499
10
                                             =
115269
10
 + x ×
499
10
    The equation is transformed into :
     
115269
10
 +
499
10
 x = 231 × 51 + 20 x
     Right side of the equation = 11781 + 20 x
    The equation is transformed into :
     
115269
10
 +
499
10
 x = 11781 + 20 x

    Transposition :
     
499
10
 x − 20 x = 11781 −
115269
10

    Combine the items on the left of the equation:
     
299
10
 x = 11781 −
115269
10

    Combine the items on the right of the equation:
     
299
10
 x =
2541
10

    The coefficient of the unknown number is reduced to 1 :
      x =
2541
10
 ÷
299
10
        =
2541
10
 ×
10
299
        = 2541 ×
1
299

    We obtained :
      x =
2541
299
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 8.498328
