2k = 69 - 39
2k/2 = 30/2
k = 15
b.) 39 + 2k = 69
39 + 2(15) = 69
39 + 30 = 69
69 = 69

Step-by-step explanation:
PEMDAS - Parenthesis, Exponential, Multiplication, Addition, Subtraction
200 – (74 + (720/9) + 44 + 16 x (4 + 6 – 8 x 2) - (42/2) + 70) – 2
200 – (74 + 80 + 44 + 16 x (-6) - 21 + 70) – 2
200 – (74 + 80 + 44 - 96 - 21 + 70) – 2
200 – 151 – 2
47
So basically, these numbers have to be consecutive because they're facing pages.
So you can just divide this by 2, and then add one to the second number.
629/2 = 314 R1
So the first page number is 314, and for the second one, just add one, and you get 315.
