[ 1/1 Equation]
    Work: Find the solution of equation 3x/(10-x) = (12-3x)/1.5x .
    Question type: Equation
    Solution:Original question:
     3 x ÷ (10 x ) = (123 x ) ÷
3
2
× x
     Multiply both sides of the equation by:(10 x )
     3 x = (123 x ) ÷
3
2
× x (10 x )
    Remove a bracket on the right of the equation::
     3 x = 12 ÷
3
2
× x (10 x )3 x ÷
3
2
× x (10 x )
    The equation is reduced to :
     3 x = 8 x (10 x )2 x x (10 x )
    Remove a bracket on the right of the equation::
     3 x = 8 x × 108 x x 2 x x (10 x )
    The equation is reduced to :
     3 x = 80 x 8 x x 2 x x (10 x )
    Remove a bracket on the right of the equation::
     3 x = 80 x 8 x x 2 x x × 10 + 2 x x
    The equation is reduced to :
     3 x = 80 x 8 x x 20 x x + 2 x x x

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

    it is concluded that::
        x1=0
    Solutions that cannot be obtained by factorization:
        x2≈3.759630 , keep 6 decimal places
        x3≈10.240370 , keep 6 decimal places
    
    There are 3 solution(s).
