[ 1/1 Equation]
    Work: Find the solution of equation 2x/(x+3)+1 = 7/(2x+6) .
    Question type: Equation
    Solution:Original question:
     2 x ÷ ( x + 3) + 1 = 7 ÷ (2 x + 6)
     Multiply both sides of the equation by:( x + 3) ,  (2 x + 6)
     2 x (2 x + 6) + 1( x + 3)(2 x + 6) = 7( x + 3)
    Remove a bracket on the left of the equation::
     2 x × 2 x + 2 x × 6 + 1( x + 3)(2 x + 6) = 7( x + 3)
    Remove a bracket on the right of the equation::
     2 x × 2 x + 2 x × 6 + 1( x + 3)(2 x + 6) = 7 x + 7 × 3
    The equation is reduced to :
     4 x x + 12 x + 1( x + 3)(2 x + 6) = 7 x + 21
    Remove a bracket on the left of the equation:
     4 x x + 12 x + 1 x (2 x + 6) + 1 × 3(2 x + 6) = 7 x + 21
    The equation is reduced to :
     4 x x + 12 x + 1 x (2 x + 6) + 3(2 x + 6) = 7 x + 21
    Remove a bracket on the left of the equation:
     4 x x + 12 x + 1 x × 2 x + 1 x × 6 = 7 x + 21
    The equation is reduced to :
     4 x x + 12 x + 2 x x + 6 x + 3(2 x + 6) = 7 x + 21
    The equation is reduced to :
     4 x x + 18 x + 2 x x + 3(2 x + 6) = 7 x + 21
    Remove a bracket on the left of the equation:
     4 x x + 18 x + 2 x x + 3 × 2 x + 3 = 7 x + 21
    The equation is reduced to :
     4 x x + 18 x + 2 x x + 6 x + 18 = 7 x + 21
    The equation is reduced to :
     4 x x + 24 x + 2 x x + 18 = 7 x + 21

    the solutions is:
        x1=
1
6
    
    There are 1 solution(s).
