327-20х=267

-20х=267-327

-20х=-60

х=3

48х+568=1000

48х=1000-568

48х=432

х=9

425/х+432=437

425/х=437-432

х=(437-432)/425

х=5/425

х=1/85

980-360:х=890

360/х=890-980

х=(890-980)/360

х=(-90)/360

6. Have you ever thought what your ideal house should be like? Read the ideas of these people and match them to the appropriate paragraphs. Are they have similar to your ideal home image?

Natalie wants to have spacious accommodation, somewhere far from bustle. It sounds quite majestic and dreamlike; however she wants the house to have all the up-to-date improvements.

Greg wants to have a rural household somewhere off-the-grid, he doesn’t mind it to be divorced from the comforts of the 21st century. He wants to hold some animal stock and grow some crops.

Irene wants to live in a comfortable place, in the countryside. She doesn’t want it to be large, but big enough to have some friends round, and some space for kids” pastime.

_____, “For me, it’s absolutely easy to say what my idea of a perfect house is. I’ve been dreaming about it since my childhood. I was brought up in such a house. My house should be my home, first of all. I mean it should be the place where I feel comfortable and welcome. I dream about a cosy house in the centre of a small quiet town, not very big but large enough for me and my family. I think it should have three bedrooms, a kitchen, a sitting room, and a big dining room with a large table. I like to entertain guests and to treat them to something tasty – that’s what I need a big dining room for. I would also like to have a small garden with flowers and fruit trees, with an arbour and some comfortable benches. There should also be a lawn and a play yard for children.”

_____, “Well, let me think… It should be large, first of all … a mansion, I think, somewhere in an isolated place, a two or three-storey building with a balcony, columns and things like that. It’s even better if it looks like a castle with towers and gates, and high walls. It’s so romantic! Plenty of rooms, staircases, an attic and a basement. It would be great if it was a real old house where ghosts live, like in fairy-tales. I could feel like a princess. But there should be all those modern conveniences like central heating, electricity, cold and hot water, gas, landline and Internet access.”

_____, “The house of my dream? Well, it would be a farm or ranch, I think. It’ll be situated near a forest, a river or a lake. You know, I like nature. The house should be a simple one, not very big, but with a large yard and fields around. I don’t need all the modern conveniences, for I won’t spend much time in there. I’d like to have some cottages or cabins also to have some rest when I get tired. There should be a garden to grow fruit and vegetables. But the main thing is the barnyard, to keep cows, sheep, horses, and pigs. I like animals and I like to take care of them.”
