Answer:
<em>112, 113</em>
Step-by-step explanation:
The pages are facing pages, so the page numbers are consecutive integers.
225/2 = 112.5
One page is 112, and the other page is 113.
Adding the 2 equations will eliminate x because -4x + 4x = 0
so we get
-14y = 28
y = -2
plug this into the second euqtion:-
4x + 14(-2) = -28
4x - 28 = -28
x = 0
answer is x = 0 , y = -2
