Question

Найдите корни уравнений x +2 3/13=10 8/39

Answer 1

$x + 2 \frac{3}{13} = 10 \frac{8}{39} \\\\ x = 10 \frac{8}{39} - 2 \frac{3}{13} \\\\ x = 10 \frac{8}{39} - 2 \frac{9}{39} \\\\ x= 9 \frac{47}{39} - 2 \frac{9}{39} \\\\ x = 7 \frac{38}{39}$

Проверка:

$7 \frac{38}{39} + 2 \frac{3}{13} = 10 \frac{8}{39}$

        $10 \frac{8}{39} = 10 \frac{8}{39}$
