Помогите пожалуйста ​

Answer 1

Ответ:

(5; -2), (1; 2)

Пошаговое объяснение:

$\left \{ {{2x - 3y= 16} \atop {x=5}} \right.$

$\left \{ {{2 * 5 - 3y = 16} \atop {x=5}} \right.$

$\left \{ {{10 - 3y = 16} \atop {x=5}} \right.$

$\left \{ {{3y = -6} \atop {x=5}} \right.$

$\left \{ {{y = -2} \atop {x=5}} \right$

(5; -2)

$\left \{ {{y=2} \atop {3x + 4y = 11}} \right.$

$\left \{ {{y=2} \atop {3x + 4 * 2 = 11}} \right.$

$\left \{ {{y=2} \atop {3x + 8 = 11}} \right.$

$\left \{ {{y=2} \atop {3x = 3}} \right.$

$\left \{ {{y=2} \atop {x=1}} \right.$
