    Work: Find the solution of equation （542+x）*34.9%+311+（542+x） = 1455 .
    Question type: Equation
    Solution:Original question:
     (542 + x ) ×
349
1000
 + 311 + (542 + x ) = 1455
    Remove the bracket on the left of the equation:
     Left side of the equation = 542 ×
349
1000
 + x ×
349
1000
 + 311 + (542 + x )
                                             =
94579
500
 + x ×
349
1000
 + 311 + (542 + x )
                                             =

349
1000
 x + (542 + x )
                                             =
250079

    The equation is transformed into :
     
521079
500
 +
1349
1000
 x = 1455

    Transposition :
     
1349
1000
 x = 1455 −
521079
500

    Combine the items on the right of the equation:
     
1349
1000
 x =
206421
500

    The coefficient of the unknown number is reduced to 1 :
      x =
206421
500
 ÷
1349
1000
        =
206421
500
 ×
1000
1349
        = 206421 ×
2
1349

    We obtained :
      x =
412842
1349
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 306.035582
