23*х+456=732
23*х=732-456
23*х=276
х=276/23
х=12

х/68+6730=7702
х/68=7702-6730
х/68=972
х=972*68
х=66096

67809-7896+y=462502
y=462502-67809+7896
y=402589

1000000-89*a=956479
89a=1000000-956479
89a=43521
a=43521/89
a=489

x-2208/32=8090
x=8090+2208/32
x=8090+69
x=8159

67*x-10986=21777
67x=21777+10986
67x=32763
x=32763/67
x=489

Once upon a time there lived a littl e boy. His name was Bill.
Bill didn't live in town. He lived in the country, and looked after
sheep. He wa s not a very good boy. He ofte n f II a sleep watching
the sheep, and he also told lies. The people who lived there often
said, "Tha t boy will come to a bad end."
One day Bill wa nted to play a practical ['pr people. He ra n down the hill and cried, "Wolf! Wolf! Help! Come
quickly! Wolf!"
All the people ran very fa st to him as they wanted to save him.
But when the people ran up to the boy they saw no wolf.
" It heard you and ran away," the boy sa id. The people went
away. Bill bega n to la ugh. "How funny the people are! How silly
they are! They are not clever at all. " Three weeks late r he wa nted to play the sa me tr ick [tr ik ] again.
"Wolf! Wolf!" he cried. "He lp! Corne quickly! Wolf!" Ma ny people
ran to the hill as fast as they could, but again there was no wolf.
This time the boy lau ghed a t them. "Ha , ha . There was no wolf," he
sa id. "What a good joke! Don't you think so?"
The people becam e ver y angry. " Lies are not jokes," they said ,
and went back horne.
Two da ys later the weather was s unny and warm. The boy was
sleeping in the afternoon sun. Suddenly he woke up. He saw a big

"Wolf!" cried the boy. "Wolf! Help! Corne quickly! Wolf!"
But nobody ca me to save the boy this time. Nobody wanted to
help him. Nobody believed him. He cried out again. He cried loudl y.
The wolf heard and said: " I like sheep , but a little boy will taste
better. I'll ha ve a real dinner toni ght! "
When the boy didn't return home that night the people went to
look for him. But they nev er fou nd him and nobod y saw him again.
