[tex]14= \sqrt{ \frac{7x}{3} }+2 [/tex]
You subtract 2 from each side.
[tex]12= \sqrt{ \frac{7x}{3} } [/tex]
Then square both sides to get ride of the radical.
[tex](12) ^{2}=( \sqrt{ \frac{7x}{3} } ) ^{2} [/tex]
Then multiply by 3 get rid of the denominator.
[tex]3(144)=3( \frac{7x}{3} )[/tex]
Then you divide by 7 to isolate X.
[tex]\frac{432}{7}= \frac{7x}{7} [/tex]
You get [tex] \frac{432}{7}or61.71[/tex]
