[ 1/1 Equation]
    Work: Find the solution of equation (x+2):x:0.25 = 4x .
    Question type: Equation
    Solution:Original question:
     ( x + 2) ÷ x ÷
1
4
= 4 x
     Multiply both sides of the equation by: x
     ( x + 2) ÷
1
4
= 4 x x
    Remove a bracket on the left of the equation::
      x ÷
1
4
+ 2 ÷
1
4
= 4 x x
    The equation is reduced to :
      x × 4 + 8 = 4 x x

    After the equation is converted into a general formula, it is converted into:
    ( x + 1 )( x - 2 )=0
    From
        x + 1 = 0
        x - 2 = 0

    it is concluded that::
        x1=-1
        x2=2
    
    There are 2 solution(s).
