Система уравнений х-2у=6; х^2+5у=10

система уравнений:

{х-2у=6

{х^2+5у=10

решаем методом постановки:

переобращуем первое уравнение:

х=6+2у;

подставляем х во второе уравнение:

(6+2у)²+5у=10;

используем формулу сокращённого умножения:

6²+2×6×2у+5у=10;

36+24у+5у=10;

действие с подобными слагаемыми:

24у+5у=10-36;

29у==-26;

у=-26/29;

х=6+2×(-26/29)= 6-13/29= 5 29/29 - 13/29= 5 16/29.

ответ: х= 5 целых 16/29;

у= -26/29.
