Suppose x = 2.
Therefore, x weeks and x days.
2 weeks and 2 days.
Total = 2*7+2 days = 16 days.
Hence 8x = 8*2 = 16 days.
Answer: 8x.
Hope it helps.

let me simplify it in a simple ways.
The question is asking us to find the total no of days in X WEEKS X DAYS.

First of all, Let's take x=2 so as per the question.
We need to find the total no of days in 2 WEEKS 2 DAYS.
so here it goes:-
1 WEEK = 7DAYS so 2 WEEKS =14 DAYS (7*2) {for 3 weeks 7*3, for 4 weeks 7*4,for 5 weeks 7*5}

"7 is always common"

So 14 days + 2 days = 16 DAYS or 7 *2 days + 2 days.
or now if we will express this equation in terms of x (i,e : Instead of 2 lets use x).

So it will be 7*x+x= 8x.
If we will use 8x to find the answer of our above equation then it will be like 8*2 = 16 DAYS

Consider value of x is 3.
1 week is 7 days.
So x weeks = 7*3 days & 3 days(x days).
If we convert consider 7*3 days(3week) & 3 days in 7*x days & x days which is equal 7x+x = 8x.

If x=4,
4 weeks + 4 days.
4*7 + 4.
32.
8 * 4 = 32.
i,e 8x = total number of days.

1 week = 7 days,
X week = 7x,
X days = x (1 day),
so,
7x + x = 8x.
