.
x - 10y = 2 (1)
x = 11y (2)
The second equation just expresses x = 11y via y.
So, substitute this expression into equation (2), replacing "x" there. You will get
11y - 10y = 2, or
y = 2.
So, you just found "y". To find "x", substitute y= 2 into equation (2) to get
x = 11*2 = 22.
ANSWER. x= 22, y= 2.
