[ 1/1 Equation]
    Work: Find the solution of equation 1500/x*6+(x-1500)/x*16% = 13.09% .
    Question type: Equation
    Solution:Original question:
     1500 ÷ x × 6 + ( x − 1500) ÷ x ×
16
100
 =
1309
10000
     Multiply both sides of the equation by: x
     1500 × 6 + ( x − 1500) ÷ 1 ×
16
100
 × 1 =
1309
10000
 x
    Remove a bracket on the left of the equation:：
     1500 × 6 + x ÷ 1 ×
16
100
 × 1 − 1500 ÷ 1 ×
16
100
 × 1 =
1309
10000
 x
    The equation is reduced to :
     9000 + x ×
4
25
 − 240 =
1309
10000
 x
    The equation is reduced to :
     8760 +
4
25
 x =
1309
10000
 x

    Transposition :
     
4
25
 x −
1309
10000
 x = - 8760

    Combine the items on the left of the equation:
     
291
10000
 x = - 8760

    The coefficient of the unknown number is reduced to 1 :
      x = - 8760 ÷
291
10000
        = - 8760 ×
10000
291
        = - 2920 ×
10000
97

    We obtained :
      x = -
29200000
97
    This is the solution of the equation.

    Convert the result to decimal form :
      x = - 301030.927835
