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?

TheSmartOne (thesmartone):
We could solve by substitution or by eliination.

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.

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):
