Помогите решить уравнение:
5x-50=60x-120

I'm a secretary at a large business. I deal with people and incoming mail. Dealing with people is one of the most important parts of my job. I find it very enjoyable I also input on the computer, send telexes and faxes.
I meet people from all over the country, all over the world, and all walks of life, which is the most interesting part of my job. They can be very nice. I think the nice ones outnumber the irritating ones. It's people-oriented job. It's communication, whether it's in person or on the telephone and that can be fun. Sometimes you have problems getting through, sometimes you get a wrong number, but it's all part of the job. You don't often get annoying people face to face. You get more of them on the phone, because people feel they can say things over the phone that they perhaps wouldn't say to your face. So I don't find people too frustrating in person. Переведите пожалуйста, только без переводчика!!
