@NickR when i have problems like that cant i just use the elimination method and then plug in whichever variable i find to get the other?because i dont like using the matrix method

anonymous · Answer

yes you can

anonymous · Answer

i knew it. our teacher makes everything so comlplicated

anonymous · Answer

lol ya i dont even remember the matrix method. and the elimination method is what abhi showed you

anonymous · Answer

yes sir! are u tired?

anonymous · Answer

little bit why?

anonymous · Answer

i have another question.
.2x-.6y=3.2
-x+1.4y=-11.2
i used eliminiation and got that x=21 y=7 and idk why thats wrong!

anonymous · Answer

x-3y=16
-x+1.4y=-11.2
-1.6y=4.8
y=-3

anonymous · Answer

x=7
