[ 1/1 Equation]
    Work: Find the solution of equation x/(2000+x) = 20% .
    Question type: Equation
    Solution:Original question:
      x ÷ (2000 + x ) =
20
100
     Multiply both sides of the equation by:(2000 + x )
      x =
20
100
(2000 + x )
    Remove a bracket on the right of the equation::
      x =
20
100
× 2000 +
20
100
x
    The equation is reduced to :
      x = 400 +
20
100
x

    Transposition :
      x
20
100
x = 400

    Combine the items on the left of the equation:
     
4
5
x = 400

    The coefficient of the unknown number is reduced to 1 :
      x = 400 ÷
4
5
        = 400 ×
5
4
        = 100 × 5

    We obtained :
      x = 500
    This is the solution of the equation.
