Answer:

x=14, y=5. (14, 5).

Step-by-step explanation:

6x-11y=29

-5x+22y=40

--------------------

5(6x-11y)=5(29)

6(-5x+22y)=6(40)

-------------------------

30x-55y=145

-30x+132y=240

---------------------------

77y=385

y=385/77=5

6x-11(5)=29

6x-55=29

6x=29+55

6x=84

x=84/6=14

x=14, y=5.
