HELP WITH EQUATIONS? PLEASE I HAVE A TEST DUE TOMORROW

TheSmartOne (thesmartone):

What equations?

OpenStudy (anonymous):

y+2x=2 y+4x=0 these two please

OpenStudy (anonymous):

What's the question

OpenStudy (anonymous):

i just posted them above

OpenStudy (anonymous):

@iambatman

OpenStudy (aripotta):

what do we need to do with them??

OpenStudy (anonymous):

i need to solve them and show work also

OpenStudy (anonymous):

Are we solving the variables, using a particular method...?

OpenStudy (anonymous):

yes

OpenStudy (aripotta):

are we trying to put them in slope intercept form?

OpenStudy (anonymous):

what do you mean?

OpenStudy (aripotta):

are we trying to solve for y

OpenStudy (anonymous):

yes

TheSmartOne (thesmartone):

We could solve by substitution or by eliination.

TheSmartOne (thesmartone):

elimination*

OpenStudy (aripotta):

y + 2x = 2 ok so to get y by itself, we have to subtract 2x from both sides

OpenStudy (anonymous):

ok

OpenStudy (aripotta):

so what do you get after you do that

OpenStudy (anonymous):

Go AriPotta!

TheSmartOne (thesmartone):

Oh like that. I thought he needed values for x and y that satisfy both equations.

OpenStudy (anonymous):

2?

TheSmartOne (thesmartone):

umm. no

TheSmartOne (thesmartone):

y=2-2x or y=-2x+2

OpenStudy (aripotta):

y + 2x = 2 -2x -2x y = -2x + 2

TheSmartOne (thesmartone):

^^

TheSmartOne (thesmartone):

and the same thing for the second one y+4x=0 What do you get? Try this one by yourself.
