Question

4. Решите уравнение (11 2/11+y)-5 4/11=8 8/11​

Answer 1

Ответ:

$(11 \frac{2}{11} + y) - 5 \frac{4}{11} = 8 \frac{8}{11} \\ \\ ( \frac{123}{11} + y) - \frac{59}{11} = \frac{96}{11} \\ \\ \frac{123}{11} + y - \frac{59}{11} = \frac{96}{11} \\ \\ \frac{64}{11} + y = \frac{96}{11} \\ \\ y = \frac{96}{11} - \frac{64}{11} \\ \\ y = \frac{32}{11} \\ \\ y = 2 \frac{10}{11} \\ \\ y = 2.90$
