Question

10/15+(5/15-х)=14/15

Answer 1

$\frac{10}{15}+(\frac{5}{15}-x)=\frac{14}{15}\\\frac{10}{15}+(\frac{1}{3}-x)=\frac{14}{15}\\ \frac{10}{15}+\frac{1}{3}-x=\frac{14}{15}\\ 1-x=\frac{14}{15}\\ -x=\frac{14}{15}-1\\ -x=-\frac{1}{15}\\ x=\frac{1}{15}$

Answer 2

Ответ:

x=1/15

Пошаговое объяснение:

10/15+(5/15-х)=14/15

(5/15-x)=14/15-10/15

5/15-x=4/15

x=5/15-4/15

x=1/15
