[ 1/1 Equation]
    Work: Find the solution of equation (x*85%+(500-x)*13.5%)/500 = 15% .
    Question type: Equation
    Solution:Original question:
     ( x ×
85
100
 + (500 − x ) ×
27
200
) ÷ 500 =
15
100
    Remove the bracket on the left of the equation:
     Left side of the equation = x ×

100000
 x +
27
200
    The equation is transformed into :
     
143
100000
 x +
27
200
 =
15
100

    Transposition :
     
143
100000
 x =
15
100
 −
27
200

    Combine the items on the right of the equation:
     
143
100000
 x =
3
200

    The coefficient of the unknown number is reduced to 1 :
      x =
3
200
 ÷
143
100000
        =
3
200
 ×
100000
143
        = 3 ×
500
143

    We obtained :
      x =
1500
143
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 10.48951
