[ 1/1 Equation]
    Work: Find the solution of equation 4/x+2x = 3/(x-3)+7/(x-2) .
    Question type: Equation
    Solution:Original question:
     4 ÷ x + 2 x = 3 ÷ ( x 3) + 7 ÷ ( x 2)
     Multiply both sides of the equation by: x  ,  ( x 3)
     4( x 3) + 2 x x ( x 3) = 3 x + 7 ÷ ( x 2) × x ( x 3)
    Remove a bracket on the left of the equation::
     4 x 4 × 3 + 2 x x ( x 3) = 3 x + 7 ÷ ( x 2) × x ( x 3)
    Remove a bracket on the right of the equation::
     4 x 4 × 3 + 2 x x ( x 3) = 3 x + 7 ÷ ( x 2) × x x 7 ÷ ( x 2) × x × 3
    The equation is reduced to :
     4 x 12 + 2 x x ( x 3) = 3 x + 7 ÷ ( x 2) × x x 21 ÷ ( x 2) × x
     Multiply both sides of the equation by:( x 2)
     4 x ( x 2)12( x 2) + 2 x x ( x 3)( x 2) = 3 x ( x 2) + 7 x x 21 x
    Remove a bracket on the left of the equation:
     4 x x 4 x × 212( x 2) + 2 x x ( x 3) = 3 x ( x 2) + 7 x x 21 x
    Remove a bracket on the right of the equation::
     4 x x 4 x × 212( x 2) + 2 x x ( x 3) = 3 x x 3 x × 2 + 7 x x 21 x
    The equation is reduced to :
     4 x x 8 x 12( x 2) + 2 x x ( x 3)( x 2) = 3 x x 6 x + 7 x x 21 x
    The equation is reduced to :
     4 x x 8 x 12( x 2) + 2 x x ( x 3)( x 2) = 3 x x 27 x + 7 x x
    Remove a bracket on the left of the equation:
     4 x x 8 x 12 x + 12 × 2 + 2 x x = 3 x x 27 x + 7 x x
    The equation is reduced to :
     4 x x 8 x 12 x + 24 + 2 x x ( x 3) = 3 x x 27 x + 7 x x
    The equation is reduced to :
     4 x x 20 x + 24 + 2 x x ( x 3)( x 2) = 3 x x 27 x + 7 x x
    Remove a bracket on the left of the equation:
     4 x x 20 x + 24 + 2 x x x ( x 2)2 = 3 x x 27 x + 7 x x
    The equation is reduced to :
     4 x x 20 x + 24 + 2 x x x ( x 2)6 = 3 x x 27 x + 7 x x
    Remove a bracket on the left of the equation:
     4 x x 20 x + 24 + 2 x x x x 2 = 3 x x 27 x + 7 x x
    The equation is reduced to :
     4 x x 20 x + 24 + 2 x x x x 4 = 3 x x 27 x + 7 x x
    Remove a bracket on the left of the equation:
     4 x x 20 x + 24 + 2 x x x x 4 = 3 x x 27 x + 7 x x
    The equation is reduced to :
     4 x x 20 x + 24 + 2 x x x x 4 = 3 x x 27 x + 7 x x

    The solution of the equation:
        x1≈2.534612 , keep 6 decimal places
        x2≈3.692476 , keep 6 decimal places
    
    There are 2 solution(s).
