Ответ:

х = 24

Пошаговое объяснение:

20 * х + 208 = 688

20 * х = 688 - 208

20 * х = 480

х = 480 : 20

х = 24

------------------------------

20 * 24 + 208 = 688

               688 = 688

3. There are six public holidays a year in Great Britain, that is days on which people need not go in to work. They are: Christmas Day, Boxing Day, Good Friday, Easter Monday, Spring Bank Holiday and Late Summer Bank Holiday. Most of these holidays are of religious origin, though it would be right to say that for the greater part of the population they have long lost their religious significance and simply days on which people relax, eat, drink and make merry.
4. Christmas day is one of their favorite holidays .It's celebrated on the 25-th of December. There are some traditions connected with it. One of them is to give presents to each other. It is not only children and members of family. It's a tradition to give Christmas presents to the people you work with. Another tradition is to send Christmas cards. All these cards are brightly and colored.
5. Most of big cities of G.B., especially London, are decorated with colored lights and Christmas trees. On Trafalgar Square, in the center of London a big Christmas tree stands. It is a gift from the people of Oslo. It is over 50 feet high. Many families celebrate Christmas day in the open air near the Christmas tree in order to catch the spirit of Christmas. Children find Christmas presents in their stockings. The traditional English dinner on Christmas is turkey and pudding.
