This is a systems of equations problem. You have two equations and two unknowns.
First:
Second: because if the pages are facing each other, then they are consecutive integers, like 134 and 135, for instance.
Substitute x+1 for y in first equation:
distribute x
solve the quadratic for 0
Factor (look for two numbers that multiply to 1332 and add or subtract to 1
x=-37, x=36
x=-37 does not make sense for this question, so x=36. Since y=x+1, y=36+1=37
Therefore the facing pages are 36 and 37.
