If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:

2d + e = 8
d - e - 4 = 0 ... d = e + 4
___________________

2d + e = 8
2 * (e + 4) + e = 8
2e + 8 + e = 8
3e = 0
e = 0

d = e + 4 = 0 + 4 = 4

(d, e) = (4, 0)

The correct result would be: C. The solution is (4, 0).
