B.no solutions
C.infinitely many
D.(2,1)

Answer 1

Okay, first you plug in what x is into the first equation

Answer 2

ugghhh yeaaah what he said.

Answer 3

3y=6(3y-4)+9
3y=18y-24+9
3y=18y-15
3y-18y=-15
-15y=-15
y=1
x=3y-4
x=3(1)-4=-1
so. x=-1 and y=1

Answer 4

A.(-1,1)

Answer 5

i got A i just didnt know if C could be an answer

Answer 6

c is not the answer , as it as unique solution
