I am down to one last attempt. Please make sure both are correct.

1) Solve the given system of differential equations by systematic elimination.

(D + 1)x + (D − 1)y	=	2
3x + (D + 2)y	=	−1

(x(t),y(t))=?

2) Solve the given system of differential equations by systematic elimination.

D²x − Dy	=	t
(D + 6)x + (D + 6)y	=	5

(x(t),y(t))=?
