Where do the following lines meet on a coordinate system? e.g. (x,y)
x+3y=4
2xy+8

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

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

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