y=y
-2x + 9 = 4x - 3
6x=12
x=2
y = 4x - 3=5
OpenStudy (hoblos):
(2,5)
OpenStudy (lifeisadangerousgame):
Thank you :) Do you think you could show me how to solve them separately too?
OpenStudy (hoblos):
separately!! what do you mean?
OpenStudy (lifeisadangerousgame):
like they're different equations one is y = -2x + 9 and the other is y = 4x - 3

Input Interpretation:
y= -2x+9
y= 4x-3
Results: x = 2 and y=5
OpenStudy (lifeisadangerousgame):
but how do I do that Hershey?
OpenStudy (hoblos):
but these are the same equations!!

^agreed

Nevermind, I just don't understand, thanks though :)
OpenStudy (anonymous):
ok....
OpenStudy (hoblos):
it is important that you understand so that you know how to solve such problems
which part you are not understanding ?
OpenStudy (anonymous):
yeah..which part do you need explaining for?
OpenStudy (lifeisadangerousgame):
I'm not sure how they're the same question

same equations
OpenStudy (lifeisadangerousgame):
equations I mean
OpenStudy (hoblos):
hmmmm do you mean why did we assume that y=y ??
OpenStudy (lifeisadangerousgame):
yea
OpenStudy (hoblos):
because that's the way to solve such problems!!
