    Work: Find the solution of equation (7+5x)/(2x)+(2+6x)/(2+x) = 11 .
    Question type: Equation
    Solution:Original question:
     (7 + 5 x ) ÷ (2 x ) + (2 + 6 x ) ÷ (2 + x ) = 11
     Multiply both sides of the equation by:(2 x )
     (7 + 5 x ) + (2 + 6 x ) ÷ (2 + x ) × (2 x ) = 11(2 x )
    Remove a bracket on the left of the equation::
     7 + 5 x + (2 + 6 x ) ÷ (2 + x ) × (2 x ) = 11(2 x )
    Remove a bracket on the right of the equation::
     7 + 5 x + (2 + 6 x ) ÷ (2 + x ) × (2 x ) = 11 × 2 x
    The equation is reduced to :
     7 + 5 x + (2 + 6 x ) ÷ (2 + x ) × (2 x ) = 22 x
     Multiply both sides of the equation by:(2 + x )
     7(2 + x ) + 5 x (2 + x ) + (2 + 6 x )(2 x ) = 22 x (2 + x )
    Remove a bracket on the left of the equation:
     7 × 2 + 7 x + 5 x (2 + x ) + (2 + 6 x )(2 x ) = 22 x (2 + x )
    Remove a bracket on the right of the equation::
     7 × 2 + 7 x + 5 x (2 + x ) + (2 + 6 x )(2 x ) = 22 x × 2 + 22 x x
    The equation is reduced to :
     14 + 7 x + 5 x (2 + x ) + (2 + 6 x )(2 x ) = 44 x + 22 x x
    Remove a bracket on the left of the equation:
     14 + 7 x + 5 x × 2 + 5 x x + (2 + 6 x )(2 x ) = 44 x + 22 x x
    The equation is reduced to :
     14 + 7 x + 10 x + 5 x x + (2 + 6 x )(2 x ) = 44 x + 22 x x
    The equation is reduced to :
     14 + 17 x + 5 x x + (2 + 6 x )(2 x ) = 44 x + 22 x x
    Remove a bracket on the left of the equation:
     14 + 17 x + 5 x x + 2(2 x ) + 6 x (2 x ) = 44 x + 22 x x
    Remove a bracket on the left of the equation:
     14 + 17 x + 5 x x + 2 × 2 x + 6 x (2 x ) = 44 x + 22 x x
    The equation is reduced to :
     14 + 17 x + 5 x x + 4 x + 6 x (2 x ) = 44 x + 22 x x
    The equation is reduced to :
     14 + 21 x + 5 x x + 6 x (2 x ) = 44 x + 22 x x
    Remove a bracket on the left of the equation:
     14 + 21 x + 5 x x + 6 x × 2 x = 44 x + 22 x x
    The equation is reduced to :
     14 + 21 x + 5 x x + 12 x x = 44 x + 22 x x

    The solution of the equation:
        x1≈-5.144293 , keep 6 decimal places
        x2≈0.544293 , keep 6 decimal places
    
    There are 2 solution(s).
