OpenStudy (anonymous):

3rd one is x=-1/3 and y=-17/3

OpenStudy (anonymous):

how did you get there?

OpenStudy (anonymous):

4th is right

OpenStudy (anonymous):

-3x+3y=-18 -x+y=-6.....eqn 1 simply add this to eqn2 4x-y=5 we get 3x=-1 or x=-1/3 put this back to eqn1 and i get y=-17/3

OpenStudy (anonymous):

i have doubt in 5th is it 2+(x/5) or (2+x)/5 ?

OpenStudy (anonymous):

(2+x)/5

OpenStudy (anonymous):

y= -19/3

OpenStudy (anonymous):
