To solve the equation \( X + \frac{2}{3} = \frac{8}{3} \), follow these steps:
- Subtract \(\frac{2}{3}\) from both sides:
\[ X = \frac{8}{3} - \frac{2}{3} \]
- Combine the fractions on the right side:
\[ X = \frac{8 - 2}{3} = \frac{6}{3} \]
- Simplify the result:
\[ X = 2 \]
So, the solution is \( X = 2 \).
