Решите системы подстановки -x - 14y = -16 4x - 19y =-16

-x - 14y = -16
4x - 19y = -16

x = 16 - 14y
4(16 - 14y) - 19y = -16

x = 16 - 14y
64 - 56y - 19y = -16

x = 16 - 14y
64 + 16 = 56y + 19y

x = 16 - 14y
75y = 80

x = 16 - 14y
y = 80/75

y = 16/15
x = 16 - 14 * 16/15

x = 16/15
y = 16/15

ответ: (16/15; 16/15)
