Select one:


a. (0, 0)

b. (10, –5)

c. (5, 10)

d. (10, 5)

Respuesta :

We can solve this system of equation by reduction method.
  d+e=15
 -d+e=-5
-------------------
      2e=10   ⇒e=10/2=5

-(d+e=15)
 -d+e=-5
-----------------
  -2d=-20   ⇒d=-20/-2=10

therefore: d=10; e=5

Answer: d.(10,5)

Answer:

(10, 5)
