[ 1/1 Equation]
    Work: Find the solution of equation (2*x+4)*(2*x-4)/(2-x)*(6-x) = (2*x+2)*(2*x-2)/(3-x)*(5-x) .
    Question type: Equation
    Solution:Original question:
     (2 x + 4)(2 x − 4) ÷ (2 − x ) × (6 − x ) = (2 x + 2)(2 x − 2) ÷ (3 − x ) × (5 − x )
     Multiply both sides of the equation by:(2 − x ) ,  (3 − x )
     (2 x + 4)(2 x − 4)(6 − x )(3 − x ) = (2 x + 2)(2 x − 2)(5 − x )(2 − x )
    Remove a bracket on the left of the equation::
     2 x (2 x − 4)(6 − x )(3 − x ) + 4(2 x − 4)(6 − x )(3 − x ) = (2 x + 2)(2 x − 2)(5 − x )(2 − x )
    Remove a bracket on the right of the equation::
     2 x (2 x − 4)(6 − x )(3 − x ) + 4(2 x − 4)(6 − x )(3 − x ) = 2 x (2 x − 2)(5 − x )(2 − x ) + 2(2 x − 2)(5 − x )(2 − x )
    Remove a bracket on the left of the equation:
     2 x × 2 x (6 − x )(3 − x ) − 2 x × 4(6 − x )(3 − x ) + 4 = 2 x (2 x − 2)(5 − x )(2 − x ) + 2(2 x − 2)(5 − x )(2 − x )
    Remove a bracket on the right of the equation::
     2 x × 2 x (6 − x )(3 − x ) − 2 x × 4(6 − x )(3 − x ) + 4 = 2 x × 2 x (5 − x )(2 − x ) − 2 x × 2(5 − x )(2 − x ) + 2
    The equation is reduced to :
     4 x x (6 − x )(3 − x ) − 8 x (6 − x )(3 − x ) + 4(2 x − 4)(6 − x ) = 4 x x (5 − x )(2 − x ) − 4 x (5 − x )(2 − x ) + 2(2 x − 2)(5 − x )
    Remove a bracket on the left of the equation:
     4 x x × 6(3 − x ) − 4 x x x (3 − x ) − 8 x = 4 x x (5 − x )(2 − x ) − 4 x (5 − x )(2 − x ) + 2(2 x − 2)(5 − x )
    Remove a bracket on the right of the equation::
     4 x x × 6(3 − x ) − 4 x x x (3 − x ) − 8 x = 4 x x × 5(2 − x ) − 4 x x x (2 − x ) − 4 x
    The equation is reduced to :
     24 x x (3 − x ) − 4 x x x (3 − x ) − 8 x (6 − x ) = 20 x x (2 − x ) − 4 x x x (2 − x ) − 4 x (5 − x )
    Remove a bracket on the left of the equation:
     24 x x × 3 − 24 x x x − 4 x x x = 20 x x (2 − x ) − 4 x x x (2 − x ) − 4 x (5 − x )
    Remove a bracket on the right of the equation::
     24 x x × 3 − 24 x x x − 4 x x x = 20 x x × 2 − 20 x x x − 4 x x x
    The equation is reduced to :
     72 x x − 24 x x x − 4 x x x (3 − x ) = 40 x x − 20 x x x − 4 x x x (2 − x )
    Remove a bracket on the left of the equation:
     72 x x − 24 x x x − 4 x x x × 3 = 40 x x − 20 x x x − 4 x x x (2 − x )
    Remove a bracket on the right of the equation::
     72 x x − 24 x x x − 4 x x x × 3 = 40 x x − 20 x x x − 4 x x x × 2
    The equation is reduced to :
     72 x x − 24 x x x − 12 x x x + 4 = 40 x x − 20 x x x − 8 x x x + 4
    Remove a bracket on the left of the equation:
     72 x x − 24 x x x − 12 x x x + 4 = 40 x x − 20 x x x − 8 x x x + 4
    Remove a bracket on the right of the equation::
     72 x x − 24 x x x − 12 x x x + 4 = 40 x x − 20 x x x − 8 x x x + 4
    The equation is reduced to :
     72 x x − 24 x x x − 12 x x x + 4 = 40 x x − 20 x x x − 8 x x x + 4
    Remove a bracket on the left of the equation:
     72 x x − 24 x x x − 12 x x x + 4 = 40 x x − 20 x x x − 8 x x x + 4
    Remove a bracket on the right of the equation::
     72 x x − 24 x x x − 12 x x x + 4 = 40 x x − 20 x x x − 8 x x x + 4
    The equation is reduced to :
     72 x x − 24 x x x − 12 x x x + 4 = 40 x x − 20 x x x − 8 x x x + 4
    Remove a bracket on the left of the equation:
