The rest is simple arithmetic.
By the way, it is not the tutor's duty to make calculations instead of you.
It is your duty, not my.
If you don't want to work at all (as you demonstrate by repeatedly posting your problem) - it is just your deal. Not my.

write two equations with two variables and show steps to solve.

-----
weight equation:: e + t = 55 oz
copper equation:: 0.11e + 0.22t = 0.17*55
-----
22e + 22t = 22*55
11e + 22t = 17*55
----
Subtract and solve for e::
11e = 5*55
e = 25 oz (amt. 11% alloy needed)
-------------
t = 55-25 = 30 oz (amt. 22% alloy needed)
