Привет! Давай разберемся с этой задачей.

Раз Pam начала делать домашнее задание на 6 минут раньше Боба, значит, когда Боб начал, у Пэм уже было 6 минут работы за плечами. Получается, что время, которое Пэм потратила на домашнее задание (p), всегда на 6 минут больше, чем время, которое потратил Боб (b).

Это можно записать так:

p = b + 6

Или, если хочешь выразить b через p:

b = p - 6

Оба варианта правильные, но обычно просят выразить первую переменную через вторую.

Ответ: p = b + 6
