I got some trouble with finding out how to calculate this..
Question: Where do these lines cross eachother x + 3y +3=0 and x - 3y +2 =0
First i tried to solve y and got this far
y = -1/3x - 1 = 1/3x+2/3 (divided all with 3)
but im not even sure if that is right. can anyone please explain how i can do this?
