    But anyways, what you're going to want to do here is use substitution. You can rearrange x-y=-10 to x = -10 + y plug it into the other equation to solve for "x" and then solve for "y".

    Is there another way? That's way too long according to my solution

    all of them will end up having to solve for y

    Ah, the GRE. Gotcha. They usually don't involve long processes. But subsitution method is the best method I can suggest. You can try to use elimination method as well, but, that might be difficult, since you have x-xy together.

    x = -10+y (-10+y) \(^2\)-2(-10+y)y = 84 the problems on the GRE are designed to take under 2 minutes. Generally, you should be going through them in about a minute and some extra seconds.

    I disagree with justifying hypersexualization of girls. it's flutterin dumb as sh1t. How you gonna say "sexual freedom" yet you're playing into the very notion of hypersexualization and objectification of women.

    feminism movement in my school (and they always end up being pissed off my me) factors out cultural relativism so I don't know who are these people you speak of

    That was a poorly constructed sentence. What do you mean factors out? Do you mean they factor in cultural relativism or don't they?
