    Answer:

    The answer is -2r + 8.

    Step-by-step explanation:

    1) Simplify 1/5(5r + 10) to 5r + 10/ 5.

    \frac{5r + 10}{5} - 3(r - 2)

    2) Factor out the common term 5.

    \frac{5(r + 2)}{5} - 3(r - 2)

    3) Cancle 5.

    r + 2 - 3(r - 2)

    4) Expand by distributing terms.

    r + 2 - (3r - 6)

    5) Remove parentheses.

    r + 2 - 3r + 6

    6) Collect like terms.

    (r - 3r) + (2 + 6)

    7) Simplify.

    - 2r + 8

    Thus, the answer for this equation is -2r + 8.
