are the same functions
OpenStudy (anonymous):
factorize the second equation 5x+5y=25 5(x+y)=25 x+y=25/5 x+y=5 they are the same !
OpenStudy (anonymous):
that means that, for any value x has in this system, there is a y that exists which respects both equations. For example x =2, y =3. x = 4, y = 1. X= 9932, y = -9927
OpenStudy (anonymous):
So the answer is None
OpenStudy (anonymous):
no, the answer is infinite because x can be anything, and y just needs to be 5 - x
