Y - 4 = 6 (x - 7) is the correct equation
The system. only really just possibly. have one solution
Answer:
X= 1, Y= 4, Z= -2
Step-by-step explanation:
(3(6x-2y-3z=4)) + (-2(9x-3y+3z=-9))
Z=-2
Substitute in Z
(6x-2y+6=4) + (3x+2y-4z=7)
X=1
Substitute in Z and X
3+2y-4=7
Y=4
I think it is d=5 because when you add them all up and divide by 5 it is 5
