I think it is c but I’m not sure
Answer:
Which one do u want help on because I can do the first 3 but not the rest
Step-by-step explanation:
-3x-y = -17
-x+y=-1
Using addition
-4x +0y = -16
-4x=-16
x=4
Then plug the value of x into one of the original equations
-x+y=-7
-(4)+y=-7
y=-7+4
y=-3
The solution is x=4 and y=-3
Thus (4,-3)
