Пошаговое объяснение:
1) (18-8х)-(2х-6)=13+х
18 - 8х -2х +6 -х = 13
-11х = 13-24
-11х = -11
х =1
2)(х+2)-(5-2х)=15-(3х+8)
х +2 - 5 + 2х = 15 - 3х - 8
6х = 10
3х = 5
х = 5/3
х = $1\frac{2}{3}$
3) (5у+3)-(2у-4)=(у-2)-(у+3)
5у + 3 - 2у + 4 = у -2 - у -3
3у = - 12
у = -4

When the man was leaving the office, another manager came up to him. "You mustn't be so honest with people," he smiled. "Next time use your imagination and make something up."
The young man went to another insurance company. The manager immediately asked him "Did your parents have any illnesses?" and "How old were they when they died?" But this time the young man was ready with an answer.
"My mother was very keen on sports. She died when she was ninety because she fell off her bike. My father was ninety-nine and died while he was playing football. He had missed the ball and was very upset about it."
The manager gave a big smile. "We must give you some life insurance right away, sir!" he said.
