    were gonna do this together okay, real simple, first, we should add the first equation to the second equation okay: 2x − 5y = 11 −2x + 3y = −9 + --------------------- What do you get?

    really? just look at this we have to add it like we would normally, it dosent matter if there are x and y's (2x)+(-2x)=0

    what? how did you get y=-1,3, from -2y=2, you have to solve for y

    if you have -2y=2, you dont know how to get y by ?itself

    okay if i have -2y=2, then what should be done is divide both sidezs by -2, that gives us y=-1

    now, simply replace y=-1 into one of your orginal equation and get x
