\(14= \sqrt{ \frac{7x}{3} }+2\)

You subtract 2 from each side.
\(12= \sqrt{ \frac{7x}{3} }\)

Then square both sides to get ride of the radical.
\((12) ^{2}=( \sqrt{ \frac{7x}{3} } ) ^{2}\)
 
Then multiply by 3 get rid of the denominator.
\(3(144)=3( \frac{7x}{3} )\)

Then you divide by 7 to isolate X.
\(\frac{432}{7}= \frac{7x}{7}\)

You get \(\frac{432}{7}or61.71\)
