Answer: A

Given:

x - y = 11
(x + y)/5 = 9
Add the two equations:

(6x + 4y)/5 = 20
6x + 4y = 100
Solve for x:

x = (100 - 4y)/6
We could have solved for x by substituting the value of y from the first equation into the second equation.
This would give us the equation:

x = 28
Substituting this value for x into the first equation, we would get:

y = 17
Therefore, the two numbers are x = 28 and y = 17.
