    You multiply everything in the parenthesis by the number outside.

    In this case its 2 and - 1. the first part is 2a-8 the second part is 4a - 2a+16a

    so it looks like this 2a-8=4a-2a+16a.

    combine like terms and get 2a-8=18a.

    Subtract the other 2a from the other side and you have 8=16a

    divide each side by 16 and you have 8/16 which is one half.
