%5CRightarrow%20(x%20-%2012)%20(y%20-%2012)%20%3D%20144

. Now

144

can be factorised into two factors

x

and

y

where

x%20%5Cle%20y

and the factors are

(1%2C%20144)%2C%20(2%2C%2072)%2C%20(3%2C%2048)%2C%20(4%2C%2036)%2C%20(6%2C%2024)%2C%20(8%2C%2018)%2C%20(9%2C%2016)%2C%20(12%2C%2012)

. Thus there are eight solutions.
