just answer the problem with steps

- abb0t

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".

- abb0t

Can you try that.

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

- nincompoop

all of them will end up having to solve for y

- anonymous

Whats another way?

- anonymous

I need to do problems like this in less than 2 minutes i'm preparing for the GRE

- nincompoop

ya that is quicker than 2 minutes

- nincompoop

you can solve the first one mentally and that is like 5 seconds

- abb0t

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.

But where does that x^2 go?

- nincompoop

nowhere, you are not to touch it

- anonymous

x^2-2xy where does that go

- nincompoop

you are only being asked for absolute value of y

- anonymous

OHHHHHHHHHHH it's replaced!!!! daaamn okay i got it BOWSSSSSSSSSSSSSSSSSS

ROSAYYYYYYYYY!!!!

So i heard you were trying to instigate an altercation by asking a certain somebody to deny feminism

- nincompoop

do you think feminism is dead?

- anonymous

Well it's going in the wrong direction.

- nincompoop

yes or no

- anonymous

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.

- nincompoop

will you be able to provide enough argument to provide the negative that feminism is dead. it is just a test of wits really nothing more and nothing less

- anonymous

I believe in empowering women but i disagree with hypersexualization and objectification of women

- nincompoop

wits and power of persuasion

- anonymous

feminism is a hard topic to discuss because theres so many different sides to it. Lot of fake feminism

- nincompoop

are you chickening out or what?

- anonymous

The free the nipple movement is stupid as sh1t since it doesn't take into considerationg the different cultural factors involved.

- anonymous

chickening out on what exactly?

- anonymous

i need to study dont have time

- nincompoop

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

- anonymous

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

- anonymous
