Answer:
there both the same cuz 23 down 23 up
Step-by-step explanation:
Use elimination.
-x = -6
X = 6
-4 (6) + 4y = 12
Y = 9
(X,y)
(6,9) is the solution
In order to figure out what N is you have to isolate it by dividing by 50 on both sides as shown below:
A) no, you can’t have duplicate x values.
B) yes it is negative linear
I believe the answer would be D, 2y+6/9y-7 x 3/2 because dividing by a fraction is the same as multiplying by its reciprocal (the fraction flipped).
Hope I helped! ;)
