Помогите решить уравнение нужно срочно!

$8 \frac{17}{36} +x+ 7 \frac{31}{36} = 25 \frac{1}{36} \\ \\ 16 \frac{12}{36} +x= 25 \frac{1}{36} \\ \\ x= 25 \frac{1}{36}-16 \frac{12}{36} = (24-16) +( \frac{37-12}{36} )\\ \\ x=8 \frac{25}{36}$

проверим:
$8 \frac{17}{36} +8 \frac{25}{36}+ 7 \frac{31}{36} = 25 \frac{1}{36} \\ \\ (8+8+7) + \frac{17+25+31}{36} = 25 \frac{1}{36} \\ \\ 23+2 \frac{1}{36} = 25 \frac{1}{36} \\ \\ 25 \frac{1}{36}=25 \frac{1}{36} \\$
