so would it be something like 8+7+4+9+9=x

I think you need to define x by saying let x = total number of hours of sleep in five days.
Then I would make a table showing
Monday 8
Tuesday 7
Wednesday etc
Thursday etc
Friday etc
Then show x = 8 + 7 + 4 etc. etc. = and add them up to give a total after the = sign. 
You got 37 hours of sleep.
