[ 1/1 Equation]
    Work: Find the solution of equation 21x(1/21+1/15)x15 = 0 .
    Question type: Equation
    Solution:Original question:
     21 x (1 ÷ 21 + 1 ÷ 15) x × 15 = 0
     Left side of the equation = 315 x (1 ÷ 21 + 1 ÷ 15) x
    The equation is transformed into :
     315 x (1 ÷ 21 + 1 ÷ 15) x = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 315 x × 1 ÷ 21 × x + 315 x × 1 ÷ 15 × x
                                             = 15 x x + 21 x x
    The equation is transformed into :
     15 x x + 21 x x = 0

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

    it is concluded that::
        x1=0
        x2=0
    
    There are 2 solution(s).
