To solve the system of equations, we can add the two equations together to eliminate d:
d + e + (-d + e) = 1 + (-5)
e + e = -4
2e = -4
e = -2
Substitute e = -2 back into the first equation to solve for d:
d + (-2) = 1
d = 3
Therefore, the correct answer is (3, -2). So the ordered pair is (d, e) = (3, -2).
(3, -2)
