  d.  (10, 5)

Step-by-step explanation:

Add the two equations, and you get ...

  2e = 10

  e = 5

Solve the first one for d and you have ...

  d = 15 -e

  d = 15 -5 = 10

So, the solution is ...

  (d, e) = (10, 5) . . . . . matches the last choice

Check

  d + e = 10 + 5 = 15

  -d + e = -10 +5 = -5
