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))=?

Please make sure you solve both correctly. 1) Solve the given system of differential equations by systematic elimination. (2D2 − D − 1)x − (2D + 1)y = 8 (D − 1)x + Dy = −8 ((x(t),y(t))= ? 2) Solve the given initial-value problem. dx dt = y − 1 dy dt = −7x + 2y x(0) = 0, y(0) = 0 x(t) = ? y(t)= ?
