</em>
<em />
<em />
<em />
<em />
To solve this system, we just need to multiply the first equation by -1, and then sum those equations.


Then, we use this value to find the other one

As you can observe, the system of equations have a unique solution.
Therefore, the answer is one solution.
It lies between -3 and -4.
An integer is any whole number, positive or negative.
