Can someone please check if I answered these 3 questions correctly?
Find three solutions:
1.x  y= 7 (10,3) (14,7) (8,1)
2.2x + y= 10 (2,6) (4,2) (5,0)
3.y=3x (2,6) (9,3) (15,5)
Thanks!

On 3. you have a couple of your answers written backwards. Remember that the first number is x and the second one y.
(x,y)
