OpenStudy (alexandervonhumboldt2):

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)

OpenStudy (alexandervonhumboldt2):

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"?

OpenStudy (triciaal):

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

Nnesha (nnesha):

yes right my pleasure

OpenStudy (dumbsearch2):

because it means that they are parallel.
