In some simultaneous equations neither the two coefficients of \(x\) nor the coefficients of \(y\) match. You will need to find numbers to multiply each equation by so that one pair of coefficients ...

We study linear jump parameter systems of differential and difference equations whose coefficients depend on the state of a semi-Markov process. We derive systems of equations for the first two ...

These can be tough, but use this method to minimise losing marks. The trick with this one is to always double check your answer by multiplying out the brackets and comparing your answer with the ...
