It has been a long time since I have taken Algebra. Now I am in a graduate Biochemistry course and I am blanking on solving what should be a simple math question. Can you give me a step-by-step solution to solving this:
$9.6=\frac{480}{Km+40}$

Solution:
$\frac{9.6}{1}=\frac{480}{Km+40}\phantom{\rule{0ex}{0ex}}Km+40=\frac{480×1}{9.6}\phantom{\rule{0ex}{0ex}}Km+40=50\phantom{\rule{0ex}{0ex}}Km=50-40\phantom{\rule{0ex}{0ex}}Km=10$
Hence. the value of Km=10
