Hi
re TY: x = 11 and y = 8 , Although: 11 + 5 = 2•8
the 2nd EQ is not satisfied : y + 4 = 2x , 8 + 4 ≠ 22
Let x and then y represent the numbers
(x+5) = 2y
y + 4 = 2x
........
x - 2y = -5
2x - y = 4
.......
-2(x - 2y = -5)
2x - y = 4
3y = 14
y = 14/3 and x = 13/3 
And..checking
y + 4 = 2x
14/3 + 12/3 = 26/3 = 2(13/3)
