Given:
The system of equation:
-------- (1)
--------- (2)
To find the values of x and y.
We will use substitution method.
From (1) we get,

We will put the value of y in (1) and we get,

or, 
Now we will apply middle term factor method.




so, x = 4 and 1
Now,
Substitute x = 4 in (1) we get,

And putting x = 1 in (1) we get,

Hence, the solution of the given system of equation is (4,-8) and (1,-5)
Thus, Option A is the correct answer.

Answer:
To determine whether a decimal is rational or not, you need to know that...
Irrational numbers don't end and have no pattern whereas rational numbers are the complete opposite. Rational numbers end and have a repeating pattern.
Step-by-step explanation:
Here are examples of irrational numbers:
0.9384903204..... , π , √2
Examples of rational numbers:
0.777777... (is rational because it has a repeating pattern of 7) , √49
