This happens if a PDE involves derivatives with respect to one variable only (or can be transformed

Question:

This happens if a PDE involves derivatives with respect to one variable only (or can be transformed to such a form), so that the other variable(s) can be treated as parameter(s). Solve for u = u(x, y):

2u_xx + 9u_x + 4u = -3 cos x - 29 sin x
