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

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

    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?

  • Algebra 2 -

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