Пошаговое объяснение:

Нехай x - ціна кефіру (у тенге). Тоді за 1 пакет молока і 1 пакет кефіру мама заплатила б 200 тенге + х тенге. Відомо, що ця сума дорівнює 345 тенге. Отже, ми можемо записати рівняння:

200 + x = 345

Розв'язавши це рівняння, отримаємо:

x = 145

Таким чином, ціна кефіру становить 145 тенге.

Щоб дізнатися, скільки коштує купівля 1 пакета молока і 1 пакета кефіру, треба просто додати ціну молока та ціну кефіру:

200 + 145 = 345

Отже, за 1 пакет молока і 1 пакет кефіру мама заплатила 345 тенге.
