write two equations that have your two intergers as a solution.Addition and subtraction methods

You have already written two equations. What do you mean by "Your" (my) two integers?
Shouldn't your second equation be 8x  9y = 21? The way you have written it,7 = 21, so y = 21
Why don't you just ask for the solution to your two equations? (I assume you meant the first y to be x in the second equation)
24x + 28y = 212
24x  27y = 63
Subtract the second from the first
55y = 275
y = 5
