[ 1/1 Equation]
    Work: Find the solution of equation (150*(1-x)+50*x)*47*0.5 = (200*(1-x)+40*x)*66*0.5 .
    Question type: Equation
    Solution:Original question:
     (150(1 x ) + 50 x ) × 47 ×

    The equation is transformed into :
     (150(1 x ) + 50 x ) ×

                                             = 3525(1 x ) + 1175 x
                                             = 3525 × 13525 x + 1175 x
                                             = 35253525 x + 1175 x
                                             = 35252350 x
    The equation is transformed into :
     35252350 x = (200(1 x ) + 40 x ) × 66 ×
1
2
     Right side of the equation = (200(1 x ) + 40 x ) × 33
    The equation is transformed into :
     35252350 x = (200(1 x ) + 40 x ) × 33
    Remove the bracket on the right of the equation:
     Right side of the equation = 200(1 x ) × 33 + 40 x × 33
                                               = 6600(1 x ) + 1320 x
                                               = 6600 × 16600 x + 1320 x
                                               = 66006600 x + 1320 x
                                               = 66005280 x
    The equation is transformed into :
     35252350 x = 66005280 x

    Transposition :
      - 2350 x + 5280 x = 66003525

    Combine the items on the left of the equation:
     2930 x = 66003525

    Combine the items on the right of the equation:
     2930 x = 3075

    The coefficient of the unknown number is reduced to 1 :
      x = 3075 ÷ 2930
        = 3075 ×
1
2930
        = 615 ×
1
586

    We obtained :
      x =
615
586
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 1.049488
