The answer is (9,21) because is you plug in 9 for x, and add 12, you get 21.
The slope is 3
whatever is in front of the x is the slope
Let us assume the first number to be = x
Let us assume the second number to be = y
Then
x^2 - y^2 = 5
x^2 = y^2 + 5
And
3x^2 - 2y^2 = 19
Multiplying the first equation by -2, we get
- 2x^2 + 2y^2 = - 10
Now subtracting the two equations, we get
x^2 = 9
x = 3
Putting the value of "x" in the first equation, we get
(3)^2 - y^2 = 5
9 - y^2 = 5
y^2 = 4
y = 2
I hope that the procedure is clear enough for you to understand and this is the answer that you were looking for.
Well, that would be 4 tables to fit 20 people but would not be enough for 2 more people so I would say 5 tables total.
-Hope this helps.
