Answer 1

@ParthKohli

Answer 2

lmao so do you

Answer 3

alrighty then

Answer 4

rather not i have work to do

Answer 5

lol @ rejection

In other news:

It isn't necessarily the best method. Best is subjective.

There really shouldn't be questions like this. Best varies from person to person. Is your question asking for anything else?

Answer 7

nope thats just the question

Answer 8

Hmm.. Welllllllll. Can you BS an answer? There isn't an objective one.

Answer 9

-2 and 1

Answer 10

x = -2 and y =1 ?

Answer 11

Wait....

Did I misread? They're asking for solutions for \(x\) and \(y\)?

Answer 12

no but i solved it with substitution

Answer 13

oh. That's the solutions, yeah.

Answer 14

x = -2, y = 1
yes

Answer 15

it just asked why it was the best method to

Answer 16

because is short and in standard form. Just 2 equations with 2 variables i is done quick. If it was more then 2 equations and more than 2 variables then use some other method.

Answer 17

oh okay thanks
