Пошаговое объяснение:

Света купила 6 карандашей по цене x руб. за карандаш. Значит она потратила 6x руб. Таня купила 2 ручки по цене в 1,8 раза выше, чем за карандаш (то есть по цене 1,8x). Значит она потратила 2*1,8x руб. После этого у девочек осталось 48,5 руб. Значит первоначально у девочек было 6x+2*1,8x+48,5=6x+3,6x+48,5=9,6x+48,5 руб. Ответ: 9,6x+48,5 руб.

Learning a foreign language is not an easy thing. It is a long and slow process that takes a lot of time and efforts. Nowadays it is especially important to know foreign languages.

Everyone, who knows foreign languages can speak to people from other countries, read foreign writers in the original, which makes your outlook wider.
It is not surprising that many intellectuals and well-educated people are polyglots. I study English. Nowadays English has become the world’s most important language in politics, science, trade and cultural relations. Over 300 million people speak it as a mother tongue. The native speakers of English live in Great Britain, the United States of America, Australia and New Zealand. English is one of the official languages in the Irish Republic, Canada, the South Africa Republic. English is one of the official languages of the United Nations Organization and other political organizations. Half of the world’s scientific literature is in English. It is the language of computer technology.
To know English today is absolutely necessary for every educated person, for every good specialist. The English language is a wonderful language. It is the language of the great literature. It is the language of William Shakespeare, Jonathan Swift, Walter Scott, Charles Dickens. The great German poet Goethe once said, “He, who knows no foreign language, does not know his own one”. That is why in order to understand oneself and environment one has to study foreign languages.
