х - меньшее число
х+14 - второе
(х+х+14)2 = 75
2х+14 = 75*2 = 150
2х = 150-14 = 136
х=136:2 = 68
68+14 = 82

My last Weekend

Yesterday it was Sunday, so my last weekend was not too long ago and I remember it quite well. I always try to do my best to make my weekend exciting, because we have only few days a week for relaxation.

Yesterday my friends and I agreed to meet at my place. First we watched a very interesting TV show “What? Where? When?” Then we took a videocassette and watched an outstanding movie “The Independence Day”. This is a story about strangers from the other planets that were trying to conquer the whole Earth and about the struggle against them. The movie was full of visual effects and computer graphics that took our breath and made us admire the modern technologies in the cinema. Having watched the film, we decided that it was a time to go outside. The first place we went to was the sports ground. Though it was rather cold, we put on warm clothes and had much fun. Almost all day we were playing soccer and basketball.

As for me, I liked my Sunday so much. During that weekend, we had an opportunity to enjoy life and have a rest.

First the writer and his friends watched a very interesting TV show. (true/false)
After watching the film, they went to the sports bar. (true/false)
They put on light clothes when they went for a walk. (true/false)
