r, minus, 1, plus, 2, rr−1+2r?

Answer 1

It seems like you're looking to simplify the expression \( r - 1 + 2r \). Let’s simplify it step by step:

1. Combine like terms. In the expression \( r - 1 + 2r \), you have \( r \) and \( 2r \) as like terms.
2. Combine \( r + 2r \): \[ r + 2r = 3r \]
3. Now the expression becomes: \[ 3r - 1 \]

So, the simplified form of \( r - 1 + 2r \) is \( 3r - 1 \).
