    \[\sqrt{3}x-2=2\sqrt{3}+4,\]then value of x is

    A)  \[2\,\,(1-\sqrt{3})\]

    B)         \[2\,\,(1+\sqrt{3})\]

    C)  \[1+\sqrt{3}\]

    D)  \[1-\sqrt{3}\]

    Correct Answer: B

    Solution :

    \[\sqrt{3}x-2=2\sqrt{3}+4\] \[\sqrt{3}x=2\sqrt{3}+6\] \[x=\frac{2\sqrt{3}+6}{\sqrt{3}}\]\[\Rightarrow \]\[x=\frac{2\sqrt{3}+6}{\sqrt{3}}\times \frac{\sqrt{3}}{\sqrt{3}}\] \[=\frac{6\,\,(1+\sqrt{3})}{3}\]\[\Rightarrow \]\[x=2\,\,(1+\sqrt{3})\]
