I realize this rather rudimentary but it has been over a decade since my algebra classes and now I have problem that I can't figure out. I would like someone to walk me through the steps in solving the "X" in this problem: $$ 1.20 \cdot 10^6 = \frac{1}{\left(\dfrac{1}{6 \cdot 10^6}\right) X} $$ So what I've done so far is this:
$$1,200,000 = \frac{1}{166,666.67X}$$
$$(166,666.67X) * 1,200,000 = \frac{1}{166,666.67X} * (166,666.67X)$$
$$200,000,004,000x = 1$$ But this doesn't make sense.
I supposed to get $x = 5$.
Thanks!
EDIT: The formula is this:
1
MTTF(system) = ---------------
n 1
E ----------
i=1 MTTFi
This is my best as I can't upload the image and not sure how else to post this. So the "E" is actually the greek letter for sumation. The "n" would be 1 since this only one system.
MTTF(system) = 1,200,000;
MTTFi = 6,000,000
