Answer:
Why is 3 an integer?
They are the numbers you usually count and they will continue on into infinity. Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4… Integers include all whole numbers and their negative counterpart e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4
The domain is all real numbers
First, multiply the first equation by 3 to get:

Then, add the two equations together to get

We can follow that x=2. Plugging in x=2, we get that y=-4.
Therefore, the solution of (2,-4)
