so first 2y=6-3x
OpenStudy (alexandervonhumboldt2):
y=3-3/2x
6x+4y=12
OpenStudy (triciaal):
using elimination
OpenStudy (alexandervonhumboldt2):
6x+4*(3-3/2x)=12
OpenStudy (dumbsearch2):
A. No solution
B. Infinitely many solutions
C. (2, 0)
D. (0, 3)

yes you are correct as the second eqauotion is half the first
OpenStudy (alexandervonhumboldt2):
B
OpenStudy (dumbsearch2):
iNFINATE? ok
OpenStudy (triciaal):
there are 4 different methods used to solve simultaneous equations. you will get the same solution but this question specified using elimination.
OpenStudy (dumbsearch2):
So the answer is "Infinitely many solutions", and not "no solution"?

this is multiple choice but if you had to show your work you would get zero
Nnesha (nnesha):
if both side equal its mean infinitely many solution ==> 0 = 0 z=z like this
if both side are not equal then no solution ==>like this 8= 9
3 =5 so
Nnesha (nnesha):
so now you can know which one is it
infinitely or no solution
OpenStudy (dumbsearch2):
Is it INFINITY, or is it NO SOLUTION?
That is MY question.
OpenStudy (dumbsearch2):
Oh, it's infinity. Thank you @Nnesha

yes right my pleasure
OpenStudy (dumbsearch2):
because it means that they are parallel.
