First we have to find the least common multiple between the denominators ( 3 and 7). Since they are prime numbers the LCM is : 3*7 = 21

Then, multiply each term of the equation by 21 and simplify


\begin{gathered} 3\cdot21+21\cdot(2)/(3)x=(2)/(7)\cdot21 \\ 63+7\cdot2x=2\cdot3 \\ 63+14x=6 \end{gathered}

The answer is 63 + 14x = 6
