any three of the above should work for ya hun
        
                    
             
        
        
        
Setup is
y = k/x
8 = k/3
k = 24
Now use 6 for y
6 = 24/x
x = 24/6 = 4 or A

Answer:
   D.  (-3, -2)
Step-by-step explanation:
The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.
Using (x, y) = (-2, -3):
   x = y -1  ⇒  -2 = -3 -1 . . . . False
Using (x, y) = (-3, -2):
   x = y -1  ⇒  -3 = -2 -1 . . . .True
   2x = 3y  ⇒  2(-3) = 3(-2) . . . . True
The solution is (-3, -2).

If you'd like to solve the set of equations, substitution for x works nicely.
   2(y -1) = 3y
   2y -2 = 3y . . eliminate parentheses
   -2 = y . . . . . . subtract 2y
   x = -2 -1 = -3
The solution is (x, y) = (-3, -2).
