[ 1/1 Equation]
    Work: Find the solution of equation 14%x+12%×(50-x) = 6.2 .
    Question type: Equation
    Solution:Original question:
     
14
100
x +
12
100
(50 x ) =
31
5
    Remove the bracket on the left of the equation:
     Left side of the equation =
14
100
x +
12
100
× 50
12

x
                                             =
14
100
x + 6
12
100
x
                                             =
1
50
x + 6
    The equation is transformed into :
     
1
50
x + 6 =
31
5

    Transposition :
     
1
50
x =
31
5
6

    Combine the items on the right of the equation:
     
1
50
x =
1
5

    The coefficient of the unknown number is reduced to 1 :
      x =
1
5
÷
1
50
        =
1
5
× 50
        = 1 × 10

    We obtained :
      x = 10
    This is the solution of the equation.
