z=228 and a=x ~> Ra z=y a=88
Detemine x and y (Finding y)
It says z = 228 then it goes to say z=y meaning y = 228
z=228 and a=x ~> Ra z=y a=88
Then it says a = x then it says that a = 88 meaning x = 88
__________________________________________________ _______
and the question is asking determine x and y ... so the final result would be like (88, 228)
I don't see anything related to chemistry in this question lol. Maybe I did it wrong... but I'm reading your question as it is lol.
