Question

y+x = 5

5x + 5y = 25

Infinite number

None

One

Answer 1

are the same functions

Answer 2

factorize the second equation 5x+5y=25

5(x+y)=25
x+y=25/5
x+y=5

they are the same !

Answer 3

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

Answer 4

So the answer is None

Answer 5

no, the answer is infinite because x can be anything, and y just needs to be 5 - x

Answer 6

oh!! o.k. I get it now
