Where do the following lines meet on a coordinate system?  e.g. (x,y)

x+3y=4
2x-y+8

Nick · Answer

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

Alan · Answer

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

Nick · Answer

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