+801 As shown in class, the Euclidean algorithm can be used to find solutions to equations of the form
\[ax + by = c.\]
Use the Euclidean algorithm to find integers $x$ and $y$ such that $266x + 357y = 1,$ with the smallest possible positive value of $x$.
State your answer as a list with $x$ first and $y$ second, separated by a comma.
Note that while there are many pairs of integers $x$ and $y$ that satisfy this equation, there is only one pair that comes from using the Euclidean algorithm as described in class, and this pair solves the problem.
