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

    The solution of the equation:
        x1≈-1.564186 , keep 6 decimal places
        x2≈0.558625 , keep 6 decimal places
        x3≈1.448580 , keep 6 decimal places
    
    There are 3 solution(s).
