Answer: (1,3)
All you're doing is looking for where the two lines cross, or the point of intersection. What you can do is draw a vertical line through this intersection point to see that the vertical line lands on x = 1 on the x axis. At the same time, draw a horizontal line to the y axis and it will get to y = 3.
So together x = 1 and y = 3 pair up to get (x,y) = (1,3)
