Where do the following lines meet on a coordinate system? e.g. (x,y)
you may have written the second equation down wrong. if it is 2x-y=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
I have just found Jiskha but i will remember for the rest of my high school carreer
