By Kirchhoff's First Law (junction rule):
At the right junction, total current leaving = $7\text{ A} + 5\text{ A} + 3\text{ A} = 15\text{ A}$. Thus, the current entering the right junction from the middle wire is $15\text{ A}$.
At the left junction, total current entering = total current leaving:
$8\text{ A} + I = 15\text{ A}$
$I = 15\text{ A} - 8\text{ A} = 7\text{ A}$
Final answer: 7 A
Final answer: 7 A
