Educational background in innovation management. All theory is nice, but I need tools to do innovation, which became computers. My main focus is on manipulating data so we can create innovations on the basis of those new insights.

Thank you. Just went through the same line of thought with @Potato.

comment How does the rewriting of the following two equations work?
This part I understand: $$(\lambda+\mu)\frac{\lambda}{\mu}P_0 = \lambda\frac{\lambda}{\mu}P_0 + \mu\frac{\lambda}{\mu}P_0$$ But when you add them up you get: $$\frac{\lambda * \lambda}{\mu}P_0 + \frac{\mu * \lambda}{\mu}P_0$$ Is it here that multiplying of the $$\mu$$ in the second part results in $$P_0$$?

I recall that, but then you would expect that somewhere you get a value along the lines this would result in: $$\frac{\lambda^2}{\mu}P_0 + \lambda P_0 + \mu P_0$$

comment Simultaneously solving of equations
@Amzoti This looks promising. I struggle a bit to understand your first step. What procedures did you go through to solve reach variable by using 1 = w + x + y + z? Did you do the following: w = 0.080w + 0.632x + 0.264y + 0.080z, which leads to 0 = 0.080w - w + 0.632x + 0.264y + 0.080z. Then add 1 = w + x + y + z to 0 = -0.920w + 0.632x + 0.264y + 0.080z and this leads to 1 = 0.08w + 1.632x + 1.264y + 1.080z. Is that the procedure you did for every line?

@GitGud The reason why the numbers are ugly is due to the fact that it comes from a markov matrix and the equation needs to be solved to obtain the stead-state probabilities of the transition matrix. As it all needs to add up to 1, things get ugly.
