Multiple Choice Answers
5, q, minus, 3, r5q−3r
6, q6q
2, q2q
9, q, minus, 3, r9q−3r

Answer 1

To simplify the expression \(7q - 3r + q + q\), we can combine like terms. We have:

1. The \(q\) terms: \(7q + q + q = 7q + 1q + 1q = 9q\).
2. The term \(-3r\) remains as is.

So combining these gives us:

\[
9q - 3r
\]

Therefore, the equivalent expression is:

\[
9q - 3r
\]

The correct answer from your multiple choice options is:
**9q - 3r**.
