Answer:
(-2, -4)
Step-by-step explanation:
Given:
The system of equations to solve is given as:
In order to solve this system of linear equations, we use substitution method.
In substitution method, we substitute the value of any one variable in the other equation.
So, we substitute the value of 'y' from first equation in the second equation.
This gives,
Dividing both sides by 3, we get:
Now, 
Therefore, the solution is (-2, -4)

Answer:
DNE
Step-by-step explanation:
As you can see in the picture I attached to this, that as the limit goes to zero from the negative side, it approaches -∞ and from the positive side, it approaches ∞ . hence, the limit doesn't exist.
To show this algebraically, you have to imagine how a number divided by zero looks like, Just know the graph of 1/x and see how the limit to zero doesnot exist. I hope this helps!
