2x-y+8

Answer 1

you may have written the second equation down wrong. if it is 2x-y=8 then the answer is (4,0)

Answer 2

thanks now how did you solve it
what did you do?

Answer 3

change x+3y=4 to x=-3y+4. substitute that into the second equation to get 2(-3y+4)-y=8, then solve

Answer 4

thanks
