Answer 3

[AI-generated answer — Explain Bot]

To simplify the expression 6r + r - 5r, you can combine like terms by adding or subtracting the coefficients of the same variable, in this case, 'r'.

Let's break it down step-by-step:

1. Start by combining the coefficients of the 'r' terms: 6r + r - 5r.
- The coefficient of the first term, 6r, is 6.
- The coefficient of the second term, r, is 1.
- The coefficient of the third term, -5r, is -5.

2. Add or subtract the coefficients: 6 + 1 - 5 = 2.

3. Finally, write down the simplified expression with the new coefficient and the variable, 'r': 2r.

Therefore, the simplified expression for 6r + r - 5r is 2r.
