Answer:
The solution to the set of linear equations is:

Step-by-step explanation:
Hey there!
In order to solve this system of equations, we can put the equations equal to each other since both equations are equal to y

Now we simplify
---> 
So now that we know that x is equal to 5, we can find the value of y
let's substitute it in one of the equations
---> 
So now we know that the point where the two equations intersect is:

This is going to be our solution
