Решить систему уравнений: 5x-2y=11 4x-y=11

$\left \{ {{5x-2y=11} \atop {4x-y=11}} \right. \left \{ {{5x-2y=11} \atop {-y=11-4x}} \right. \left \{ {{5x-2y=11} \atop {y=4x-11}} \right. 5x-2(4x-11)=11 5x-8x+22=11 -3x=11-22 -3x=-11 3x=11$
$x= \frac{11}{3}= 3\frac{2}{3}$
$5* \frac{11}{3}-2y=11$
$18\frac{1}{3}-2y=11;-2y=11- 18\frac{1}{3};-2y= -7\frac{1}{3};y= 3\frac{2}{3}$
Ответ: $(3\frac{2}{3}; 3\frac{2}{3})$
