What is the solution to this system of linear equations?

y − x = 6

y + x = −10

1.(−2, −8)
2.(−8, −2)
3.(6, −10)
4.(−10, 6)

Respuesta :

Answer:

(-8, -2)

Step-by-step explanation:

Combine these equations:  You'll get 2y = -4, so that y = -2.

Substituting -2 for y in the second equation, you'll get -2 + x = -10, or x = -8

Thus the solution is (-8, -2)
