Merging id to multiple tables in phpmyadmin

[intern3t]

i have a table :chapter1and2 with columns: id, agree_1, comment_1, agree_2, comment_2

and another table:chapter3 with columns: id, agree_3, comment_3, agree_4, comment_4

and another table: chapter4 with columns: id, agree_5, comment_5, agree_6, comment_6

and another table: users with columns: id , firstname, lastname, phone, ....

the idea is , when a user logs in, he or she is ment to vote. chapter1and2 is on one page, chapter 3 is on a different page, and so is chapter4.when he or she votes, her id on users table must be the same with id on the chapters. How do i join the whole tables with id to achieve this aim? thanks for reply
