[ Answer ]
[tex]\boxed{B \ = \ 16 }[/tex]
[ Explanation ]
-17 + [tex]\frac{B}{8}[/tex] = -15
Add 17 To Both Sides:
-17 + [tex]\frac{B}{8}[/tex] + 17 = -15 + 17
Simplify:
[tex]\frac{B}{8}[/tex] = 2
Multiply Both Sides By 8:
[tex]\frac{8B}{8}[/tex] = 2 · 8
Simplify:
B = 16
[tex]\boxed{[ \ Eclipsed \ ]}[/tex]
