    Exclamation Help with Basic Simultaneous Equation? THANK YOU!

    Question:

    Solve the following simultaneous equations.

    8x-2y=6
    2x-y=1

    I know how to solve it by substitution but i can't seem to solve it using the elimination method.
    I tried using elimination but I kept getting a fraction for my answer (which is wrong.)

    Can anybody show me how to solve this using the elimination method?

    Thank you very much!!! I would really appreciate the help!

    Mistakes aren't dumb. (Well, okay, there are a few...) In any event mistakes merely indicate part of the learning process. Don't demean yourself!

    There are two ways to this by elimination:
    1) multiply the second equation by 2 so that both have "2y" and subtract from the first, eliminating y.

    2) multiply the second equation by 4 so that both have "8x" and subtract from the first, eliminating x.
