1. The problem statement, all variables and given/known data assuming dy/dt = Dy, d^2y/dt^2 =D^2, etc: determine the general and particular solutions to the following linear pair of differential equations: 2D^2y-Dy-4x=2t 2Dx-4Dy-3y=0 2. Relevant equations 3. The attempt at a solution I have went through algebraic manipulation to come up with the first equation: 16D^4x+4D^3x-6D^2x-4x=2t. It was close, but wasn't an equidimensional equation. Now I would have to solve this- but a 4th order equation that isn't linear? Thanks in advance!
