How do you solve the following system?: #11x -17y =11, -59x -67y = -7#
Seriously??? This question is just ugly! All the numbers are primes numbers so the products are big and cumbersome..
However, it is of some comfort that even in a case like this, a method can be used to find an answer.
To keep the numbers as small as possible, let's change them both into
Now, using the fact that
It means that
Cross multiply to get:
