Answer 1

Ответ:

y=25    x= -20 2/3

Пошаговое объяснение:

$\left \{ {{6x+5y=1} \atop {2x-3y=33}} \right.=\left \{ {{6x+5y=1} \atop {-6x+9y=-99}} \right. \\\\-4y=-100\\y=-100:(-4)\\y=25\\\\6x+5y=1\\6x+5*25=1\\6x+125=1\\6x=1-125\\6x=-125\\x=-125:6\\x=\frac{-124}{6}\\\\ x=-\frac{62}{3}\\\\ x=-20\frac{2}{3}$
