помогите, пожалуйста, дам 40 баллов

Answer 1

Ответ:

x = 24; y = 10.

Объяснение:

$\left \{ {{x-y = 14} \atop {\frac{x}{y}\ = \ 2.4 }} \right\\\\x = 14+y\\\frac{14+y}{y} = 2.4\\\frac{14+y}{y} = \frac{12}{5} \\y+14 = \frac{12y}{5}\\y = \frac{12y}{5}-14\\y = 2.4y-14\\-2.4y+y = -14\\-1.4y = -14\\1.4y = 14\\\\y = 14/1.4 = 10\\\\x = 14+10 => x = 24.$
