Question

найдите корень уравнения x + 5 целых 2/5= 10​

Answer 1

Ответ:

$x + 5 \frac{2}{5} = 10 \\ x = 10 - 5 \frac{2}{5} \\ x = \frac{50}{5} - \frac{27}{5} \\ x = \frac{50 - 27}{5} \\ x = \frac{23}{5} \\ x = 4 \frac{3}{5}$

Answer 2

$x+5\frac{2}{5}=10\\x+\frac{27}{5} = 10\\x = 10 - \frac{27}{5}= \frac{50}{5}-\frac{27}{5}= \frac{50-27}{5}=\frac{23}{5}=4\frac{3}{5}$
