Просто :)
Переносим 2x в левую сторону, а 7 в правую, и получаем уравнение вида 3x+2x=13+7
Складываем и получаем 5x=20. отсюда x=4.

Karabay and Sarybay were very good friends and they
promised that their children would marry. Sarybay died
before his son Kozy was bom. Karabay had a daughter
called Bayan Kozy and Bayan grew up but they didn't meet.
Bayan became a beautiful young woman. The fame of her
beauty spread throughout the whole steppe. She became
known as Bayan-Sulu, or "Bayan the Beautiful: Kozy and
Bayan finally fell in love
Then a warrior called Kodar helped Karabay rescue his goats
and sheep in the desert. So Karabay changed his mind
and decided to give his daughter to Kodar instead of Kozy,
But Bavan didn't love Kodar and wanted to wait for Kozy.
So Karabay and Kodar took Bayan away. On the way she
dropped some of her things. On a mountain, she left her
comb and then she dropped her belt and necklace. Kozy
followed her things and found her. Then Kodar attacked
Kozy and they had a fight. Kodar lost the fight but then
murdered Kozy in his sleep.
Bayan took her revenge. She asked Kodar to bring water from a deep well, Kodar climbed
down into the well using her hair braids as a rope. But then Bayan cut them and Kodar die
