Answer:
The solution for given system of equation is:
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
Step-by-step explanation:
we can solve the system of equations to find the value of x and y and then verify if (1,3) is a solution or not.
The system of equation given is:

Solving:
Let:

Put value of y from equation 2 into equation 1

Now, put value of x in equation 2 to find value of y

So, the solution for given system of equation is:
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
