To simplify the expression \( \frac{3}{7}x + \frac{2}{7}x \), you can combine the terms since they have the same denominator:
\[ \frac{3}{7}x + \frac{2}{7}x = \left( \frac{3 + 2}{7} \right)x = \frac{5}{7}x \]
So, the simplified expression is:
\[ \frac{5}{7}x \]
The correct response is:
Start Fraction 5 over 7 End Fraction x.
