The left and right page numbers of an open book are two consecutive integers whose sum is 433. Find these page numbers

Step-by-step explanation: denoting the numbers by x and x + 1, we can write: x + x + 1 = 433

2x + 1 = 433

2x = 433 - 1

2x = 432

x = 432/2

x = 216

Therefore, the unknown numbers are

216 e 217.
