Simplify 3/7x + 2/7x

To simplify the expression \( \frac{3}{7}x + \frac{2}{7}x \), we can combine the terms since they have a common coefficient.

1. Add the coefficients: \( \frac{3}{7} + \frac{2}{7} = \frac{3 + 2}{7} = \frac{5}{7} \).

2. Since both terms include \( x \), we keep \( x \) in the result.

So the simplified expression is:

\[ \frac{5}{7}x \]

Thus, the correct response is:

5/7x (Start Fraction 5 over 7 End Fraction x).
