The sum of two numbers
x + y = 21
x = smaller number
y = larger number
Larger Number = y = (2x -6)
Substitute (2x - 6) for y
x + y = 21
x + (2x - 6) = 21
3x - 6 = 21
3x = 21 + 6
3x = 27
3x / 3 = 27 / 3
x = 9
Smaller number = x = 9
Find the larger number by inserting 9 into (2x - 6)
(2x - 6)
(2(9) - 6)
18 - 6
12
So
x = 9
y =12
Check our answer by inserting x = 9 and y = 12 into x + y = 21
x + y =21
9 + 12 = 21
21 = 21
So since we have 21 = 21 we know our answer is correct.

Answer:
A = 51 pages
N = 71 pages
Nolan will be 20 pages farther along in the book than Addison after 4 days.
Step-by-step explanation:
for Addison if you multiply 11 by 4 you get 44 then you add 7 you get 51
For Nolan if you multiply 6 by 4 you get 24 then you add 47 and you final answer is 71
As 
, the 
term will converge to 0, so the limit is 2 (B).
