and
. So we have a remainder of

and
. Subtracting this from the previous remainder gives a new remainder

and
. Subtracting this from the previous remainder gives a new one of

and we're done since 2 does not divide
. So we have

We have to sum 8 and two-third of x, so we must multiply x by 2/3 and sum it with 8,
thus, the expression is
