anonymous · Answer

A.
1
 
 B.
2
 
 C.
infinitely many
 
 D.
0

hartnn · Answer

plug in the value of y from 2nd equation into 1st equation

that is put y =2/3 x+1 in 6x-9y=-9

anonymous · Answer

just 2, because the second one seems like its for y, and there's only x and y we have to solve for, so 2

anonymous · Answer

hmmm....so @hartnn are you saying 2 or not not

hartnn · Answer

no, there are more than 2
how ? we need to find out
so did u do what i asked for ?

anonymous · Answer

well 
6x -9(2/3x+1) = -9
6x -6x -9        = -9
0                     = 0

anonymous · Answer

yes i plugged it in

anonymous · Answer

now what

hartnn · Answer

what did u get ?

anonymous · Answer

so its 2

hartnn · Answer

@jvlinh so which 2 solutions you got ?

anonymous · Answer

6x-9(y =2/3 x+1)=-9

anonymous · Answer

is what i got

anonymous · Answer

only x and y are in there, and the second only has y, so 2?

anonymous · Answer

is it true @hartnn

hartnn · Answer

thats not the way to solve
and no

hartnn · Answer

"
6x -9(2/3x+1) = -9
6x -6x -9        = -9
0                     = 0"

did u get that process^ ??

hartnn · Answer

we got 0=0, right ?
is it true for any values of x and y ??
or for only some values ?

hartnn · Answer

you still here ? @TakeA.I.M. ?

anonymous · Answer

yes sry i was gone for a min

anonymous · Answer

its true for values x and y right?

hartnn · Answer

yes, for all or any values of x and y
thats why we have infinite solutions :)

anonymous · Answer

ok thnx
