how many solutions does the system have?
x2y=6
3x6y=18
a)1
b)2
c)many
d)none

2y=66
2y=0
y=0 ans.
Proof:
3*66*0=18
18+0=18
18=18
One solution: (6,0).

thanks Rezu

If you triple the first equation , you will get the 2nd
so there is only one equation,
and there is an infinite number of solutions.
Rezu gave you only one
here is another (2,2)
and another (0,3) etc

algebra1  jenika, Thursday, May 17, 2012 at 7:55pm
so infinite or just one?

algebra1  Reiny, Thursday, May 17, 2012 at 7:58pm
come on!
I already gave you more than one.
