Add the two equations together:
−3x − y = −11 +
−3x + y = 29
––––––––––––––
-6x = 18
x = -3
Plug this into either equation:
−3x + y = 29
−3(-3) + y = 29
9 + y = 29
y = 20
SOLUTION: x = -3, y = 20
Note that if you graphed both lines, they'd intersect at (-3, 20)

3x+y=11,y-3x=29,add equations 1 and 2,2y=40,therefor,y=20. Substitute 20 for y in the 1st equa. Gvng 3x+20=11,therefore,3x=-9,x=-3,, x=-3,y=20
