Simplify the expression 3/5x + x.

1. 6/5x

2. 8/5x

3. 9/5x

4. x

The correct answer is: 6/5x

To simplify the expression \( \frac{3}{5}x + x \), it's helpful to express \( x \) in terms of a fraction that has a common denominator. Since \( x \) can be written as \( \frac{5}{5}x \), we can rewrite the expression as follows: \[ \frac{3}{5}x + \frac{5}{5}x \] Now, when adding these two fractions, we combine the numerators while keeping the denominator the same: \[ \frac{3 + 5}{5}x = \frac{8}{5}x \] This shows that the correct answer is \( \frac{8}{5}x \), reflecting the total of both terms. Therefore, the initial answer given was not correct, as the simplified form of the expression is indeed \( \frac{8}{5}x \).
