The left and right page numbers of an open book are two consecutive integers whose sum is 449. Find these page numbers.
The two page numbers are
(Use a comma to separate answers as needed.)
Let's assume the left page number is x and the right page number is x + 1.
According to the given information, the sum of the left and right page numbers is 449:
x + (x + 1) = 449
Combining like terms:
2x + 1 = 449
Subtracting 1 from both sides:
2x = 448
Dividing both sides by 2:
x = 224
So the left page number is 224 and the right page number is 224 + 1 = 225.
The two page numbers are 224, 225.
