    cheating for what? I don't know how to do this question so I'm posting. And you spelled "site" wrong.

    Here we have 3 equations and 4 unknowns. I believe this problem is indeterminate.

    i never said I want a straight answer. Do you have something against me? Why are you picking on me?

    that's the whole problem. What happens if the person comes up with a different answer other than the choices?

    The best I can do is give you a in terms of either b, c or d.

    jeez people are so touchy these days @sussycake there are more variables than equations here, so either there is a typo, one equation is missing, or the problem is posed incorrectly you can solve for one variable in terms of others, but you cannot assign a number to the variables

    Ok, I got a=0, but that's obviously not right.
