    1. subtract 4 from 8;

    4 (m+5) = 3 (m-9)

    2. distribute:

    4m+20=3m-27

    3. subtract 20 to both sides:

    4m=3m-47

    4. subtract 3m from both sides:

    m=-47

    8 - 4m - 20 = 3m - 27

    - 4m - 12 = 3m - 27

    +4m + 4m

    - 12 = 7m - 27

    +27 + 27

    15 = 7m

    m = 15/7
