1 уравнение: 3х - 15 - 1 - 6 + 2х = 0
5х = 22 ---> x = 22/5 = 4.4
2 уравнение: 3х - 3у - 7у + 4 = 0
3х - 10у + 4 = 0
10у = 3х + 4
у = 0.3х + 0.4 = 0.3*4.4 + 0.4 = 1.32 + 0.4 = 1.72
Ответ: (4.4; 1.72)

Back to the FUTURE

In the early 1980s, the television series Knight Rider featured a talking, thinking car that could drive itself. 1 The idea of a car that drives itself was science fiction until very recently.

Today, engineers all over the world are working to create smartcars. 2 They will be able to talk to your tablet or laptop computer, your smartphone, other cars, and almost any other device. Some cars will even be able to drive themselves while the driver sits back and relaxes or surfs the Internet. They'll help drivers save time and energy and watch out for other cars and pedestrians. 3

Future cars will also be able to do other things such as remind you to meet someone or to take your medicine. Engineers say that future cars will also be able to get to know the driver by using a video camera to watch their face and recognise their emotions. 4 Future driving is going to be very happy driving.

A They'll even be able to choose their own routes so as not to get stuck in traffic jams.

B When the driver is in a bad mood, it will try to cheer them up.

C In each episode, the main character jumped in the car, gave it instructions and the car did the rest.

D Everybody will want to have their own smartcar. E These cars will be safer, environmentally friendly, and more intelligent.

Hi Cathy,
I’ve got a new flat – it’s great! There ’s a kitchen, living room and bedroom. And there ... a bathroom, of course. There ... a bath but it’s got a shower – I love showers! The bedroom’s quite big. There ... a bed and a wardrobe but there ... any shelves. The living room is my favourite room. There ... two armchairs, a sofa and a TV. There ... also a roof terrace and there ... lots of plants!
And your flat? Has it got a roof terrace?
... there any plants? ... there Wi-Fi? ... there a phone? Send me the number and I can phone you!
