add the two equations together so u get 6x=16 divide both sides by 6 x=16/6 simplify x=8/3

OpenStudy (shamil98):

@ngott3 that's wrong

OpenStudy (shamil98):

3x + 3y =27 x - 3y = -11 adding them you get 4x = 16 storm can you do it from here?

OpenStudy (shamil98):

once you find x sub it back into x - 3y = -11 to get your value for y.
