Ok what I have done is take L.T's, which gives me this:
dont know what the symbol here is but its always Y bar
3(sy - 1) +4y = 4/s + 6/s^2 + 8/s^3
So then I get:
y(3s + 4) = 4/s + 6/s^2 + 8/s^3 + 3
I dont know how to proceed from here. I could obviously divide the rand hand side by (3s+4) but im not completely certain if I need to do anything else first.
