In elimination method you add/subtract both equations to cancel out a variable so you can solve for 1 variable.

since there is +y in the first equation and +y in the second equation, you can subtract both equations from eachother to only be left with x values:

(2x+y=11) (subtract each term)
- (x+y=9)

you get x=2.

now sub in x=2 to any of the 2 equations to find what y is.

2(2)+y=11
y=7

so the answer is (2,7) which means the 2 lines intersect at the point (2,7)
