Ответ:
(x, y) = (-12, 10)
Step-by-step explanation:
9x + 11y = 2 (1)
3x + 4y = 4 (2)
Multiply equation (1) by 4 and equation (2) by 11, then subtract equation (2) from (1),
4(9x + 11y) - 11(3x + 4y) = 8 - 44
36x + 44y - 33x - 44y = -36
3x = -36
x = -12
From equation (2),
-3(12) + 4y = 4
-36 + 4y = 4
4y = 4 + 36
4y = 40
y = 10
