Answer:
B) consistent, dependent
Step-by-step explanation:
The given system is
45x - 30y = -90
-12x + 8y = 24
Let us make y the subject in both equations to get:
Top equation

Bottom equation

We can see that both equations are identically the same.
There is going to be infinitely many solutions.
We say the system is consistent and dependent.
The correct choice is B
The answer would be the first one
- 1 1/3 - 2 1/5
= -4/3 - 11/5
= -20/15 - 33/15
= -53/15
= -3 8/15 mg/L
