Answer:
x=4 and y=2
Explanation:
I'm not 100% sure but I substituted different numbers into the equation:
If x=4 and y=2 then 4+2=6 and 3x2=6 so it would be 6=6
Another option is x=7 and y=3 then 7+2=9 and 3x3=9 so it would be 9=9
I'm more confident with x=4 and y=2 because of the small size of the triangle.
I hope this helps! Good luck! :)
