x+y=9
x-y=-3

Answer 1

found that x = 3 and y = 6. not sure what kind of system it is but at least you can graph it with this info.

Answer 2

it"s so easy. x=3,y=6

Answer 3

you can do it yourself.

Answer 4

\[just cut the "y" \because they have different signs and do 9-3 so you can find the "x" after that you replace x for 6 so you can find the y :)
