Question

Решите систему уравнений:​

Answer 1

Объяснение:

$4x - 5y = 18 \\ x = 2 \\ \\ 4 \times (2) - 5y = 18 \\ 8 - 5y = 18 \\ - 5y = 18 - 8 \\ - 5y = 10 \\ y = - 2 \\ (x;y) = (2; - 2)$

-------------------------------------------------

$y = 3 \\ x + 3y = 14 \\ \\x + 3 \times (3) = 14 \\ x + 9 = 14 \\ x = 14 - 9 \\ x = 5 \\ \\ (x;y) = (5;3)$
