Step-by-step explanation:
Answers: #2, 3, 5, 6 are correct
... believe me, I juss did them.
Solve the system of equations by the addition method.
6x - y = 12
6x + y = 0
——————
12x = 12
12x/12 = 12/12
X = 1
Now plug x back into one of the equations.
6x + y = 0
6(1) + y = 0
6 + y = 0
(Subtract both sides by 6)
Y = -6
-21 + 3n = -18 + 2 -6 = -22 . I believe this is right. I hope I made sense, and just pls correct me if I’m wrong!
