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

algebra1 
Rezu,
2y=66
2y=0
y=0 ans.
Proof:
3*66*0=18
18+0=18
18=18
One solution: (6,0).

jenika,
thanks Rezu

algebra1 
Reiny,
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

jenika,
so infinite or just one?

algebra1 
Reiny,
come on!
I already gave you more than one.
How many points lie on a straight line??????
