From 1, x = 5,17,29,41,53,65 etc... Dividing by 8 has remainders 5 or 1

1) When x is divided by 12 the remainder is 5
2) When x is divided by18 the remainder is 11

From (1) x=12k+5 could be 5,17,29,41,53,65 NOT SUFF
From (2) x=18m+11 could be 11,29,47,65 NOT SUFF

Combining (1) and (2), x could be 29 or 65, each with a different remainder when divided by 8 NOT SUFF
