The answer is 6. You just have to replace the values and done.
I think the anwser is team y has 4 points and team x has 12 points because 4×3=12-4=8 so team x has 3× the points team y does and has an 8 point lead.
hope this helps and dont forget to hit that heart :)
Since the triangle is equilateral (you can tell by the tick on each side), all angles have the same measure as well.
The angles of a triangle sum up to 180 degress, so three equal angles must measure 60 degrees each.
So, in particular, we have
7x + 4 = 60 7x = 56 x = 8
