Question

The left and right page numbers of an open book are two consecutive integers whose sum is 347. Find these page numbers.

The smaller page number is
The larger page number is

Answer 1

Let the first page = x

The second page would be x + 1

Add them together to equal 347

X + x + 1 = 347

Combine like terms:

2x + 1 = 347

Subtract 1 from both sides

2x = 346

Divide both sides by 2:

X = 173

The smaller page number is 173

The larger page number is 174
