Answer:
7 in both boxes
Step-by-step explanation:
In the picture, it shows 
4 (x - 3) = 20
and then it shows
4 (x) - 4 (3) = 20
 so practically you separate the x and 3 and put them in parentheses and then put a 4 next to both of them.
It should be the same as your question.
7 x (8 - 3) 
and then separate 8 and 3 and put a 7 next to both of them.
( 7 x 8) - ( 7 x 3)
