Zoe reads 120 pages of a series in the first week and the number of pages she reads increases by 12 each subsequent week. Adam reads 180 pages in the first week and the number of pages he reads increases by 4 each subsequent week.
After how many weeks will Zoe and Adam have read the same total number of pages.
