Linear Partial Differential Equation---Problem in solving?? Hi guys! im getting stuck in solving the following Linear Partial Differential Equation: 2p+3q=x+y+1 now when i just form its auxiliary equation it becomes dx/2 = dy/3 = dz/(x+y+1) Now the problem that im just facing is how to solve these three sides. Usually i try to divide and multiply by some constant and then add these three. But in this case, i just couldnt find a way to go! please help me as soon as possible! thanks in advance!
