Getting the solution of two linear equations, we can apply method related to that.

We can uses simple elimination by adding the two equations.
d + e = 1 
−d + e = −5 
------------------
2e = -4
e = -2

d + e = 1
d - 2 = 1
d = 3

so the solution is in the form (d,e) is (3, -2)

So the answer is (3,-2).
