Set up two brackets. Since 7 only has two factors, put 7x in one bracket and x in the other. The two other numbers will be a factor pair of 16 (16,1)(8,2)(4,4). Since the signs are minus, one of the brackets will be plus and one will be minus. Now you just have to put it together in a way that fits. We used to call that trial and error, now it's called guess and check.
