[ 1/1 Equation]
    Work: Find the solution of equation 14/x+8 = 10/(3x+24)+4/x .
    Question type: Equation
    Solution:Original question:
     14 ÷ x + 8 = 10 ÷ (3 x + 24) + 4 ÷ x
     Multiply both sides of the equation by: x  ,  (3 x + 24)
     14(3 x + 24) + 8 x (3 x + 24) = 10 x + 4 ÷ 1 × 1(3 x + 24)
    Remove a bracket on the left of the equation::
     14 × 3 x + 14 × 24 + 8 x (3 x + 24) = 10 x + 4 ÷ 1 × 1(3 x + 24)
    Remove a bracket on the right of the equation::
     14 × 3 x + 14 × 24 + 8 x (3 x + 24) = 10 x + 4 ÷ 1 × 1 × 3 x + 4 ÷ 1 × 1 × 24
    The equation is reduced to :
     42 x + 336 + 8 x (3 x + 24) = 10 x + 12 x + 96
    The equation is reduced to :
     42 x + 336 + 8 x (3 x + 24) = 22 x + 96
    Remove a bracket on the left of the equation:
     42 x + 336 + 8 x × 3 x + 8 x × 24 = 22 x + 96
    The equation is reduced to :
     42 x + 336 + 24 x x + 192 x = 22 x + 96
    The equation is reduced to :
     234 x + 336 + 24 x x = 22 x + 96

    After the equation is converted into a general formula, it is converted into:
    ( 2x + 15 )( 3x + 4 )=0
    From
        2x + 15 = 0
        3x + 4 = 0

    it is concluded that::
        x1=-
15
2
        x2=-
4
3
    
    There are 2 solution(s).
