[ 1/1 Equation]
    Work: Find the solution of equation 300x7%+X = （300十X）x10% .
    Question type: Equation
    Solution:Original question:
     300 x ×
7
100
 + x = (300 + x ) x ×
10
100
     Left side of the equation = 21 x + x
                                             = 22 x
    The equation is transformed into :
     22 x = (300 + x ) x ×
10
100
    Remove the bracket on the right of the equation:
     Right side of the equation = 300 x ×
10
100
 + x x ×
10
100
                                               = 30 x + x x ×
10
100
    The equation is transformed into :
     22 x = 30 x + x x ×
10
100

    After the equation is converted into a general formula, it is converted into:
    ( x + 80 )( x - 0 )=0
    From
        x + 80 = 0
        x - 0 = 0
    it is concluded that:：
        x1=-80
        x2=0    
    There are 2 solution(s).
