Q 1.(a) Reduce the following PDE equation via Characteristic to ODES(No need to solve them) in terms of y=y(x), u=u(x) and u=u(y) (3 + x?)ux + (4 + x * y)uy = 5u + 3 (b) Reduce the following PDE equation to ODES via separable method only(No need to Integrate them) in terms of y=y(x), u=u(x) and u=u(y) (i) 3ux + 4uy = 0 %3D (ii) 5uxx + 3uyy + 4uzz = 0
