3)1/4х+2=х
2=1х - 1/4х
2=4/4х-1/4х
2=3/4х
х=2 : 3/4х
х=2/1*4/3
х=8/3= 2целых 2/3
Как то так !
Проверка:
1/4*2цел.2/3+2=2цел.2/3
1/4*8/3+2=2цел.2/3
( 4 и 8 сокращаются на 4)
2/3+2=2цел.2/3
2цел.2/3=2цел.2/3

Why do I want to go to America. Let's say, because I really like this country. She is very big and beautiful. There are a lot of cities in it. I want to see New York, Los Angeles and Disneyland. I want to see Niagara Falls. See the statue of liberty. In America they make my favorite phones and Arles watches. I wonder what Hollywood is and how movies are made there. See the Florida cosmodrome and crocodiles. I want to lie on the beaches of Mayami. I want to take a paddle boat trip on the Mississippi River. Visit the White House. To see the president of a great country. !
