[ 1/1 Equation]
    Work: Find the solution of equation (2x-1)/(3x+4) = 60% .
    Question type: Equation
    Solution:Original question:
     (2 x 1) ÷ (3 x + 4) =
60
100
     Multiply both sides of the equation by:(3 x + 4)
     (2 x 1) =
60
100
(3 x + 4)
    Remove a bracket on the left of the equation::
     2 x 1 =
60
100
(3 x + 4)
    Remove a bracket on the right of the equation::
     2 x 1 =
60
100
× 3 x +
60
100
× 4
    The equation is reduced to :
     2 x 1 =
9
5
x +
12
5

    Transposition :
     2 x
9
5
x =
12
5
+ 1

    Combine the items on the left of the equation:
     
1
5
x =
12
5
+ 1

    Combine the items on the right of the equation:
     
1
5
x =
17
5

    The coefficient of the unknown number is reduced to 1 :
      x =
17
5
÷
1
5
        =
17
5
× 5
        = 17 × 1

    We obtained :
      x = 17
    This is the solution of the equation.
