x + 2y = 8

(3, 2)

(2, 3)

(-2, -3)

(-2, 3)

Answer 1

brb

Answer 2

4x+y=11
x+2y=8

take the second equation:

x+2y=8

make it x=
so

x=8-2y

then plug that back into the first equation

4(8-2y)+y=11
32-8y+y=11
32-7y=11
-7y=-21
7y=21
y=3

now plug y into the second equation and solve.
then youll have your x an y
