Please help me:

I have two simultanous equations - can you help me solve them, so that
i can do an inverse laplace transform on them:

(2-s)x - 3y = 8

(1-s)y - 2x = 3

Also i have come to a problem with the following:

Once i have derived the equations, i can't seem to derive the 2
simultaneous diff equations  again to solve x and y using lapace:

z = x + y

30z - 110  + 2 dx/dt + 10x  = 0

-10x - 2 dx/dt  + 4 dy/dt  + 20y   = 0

Please help!

A positive reply would be greatful.
