7 girls participated only in Karate.
21 + 8 = 29
29 + 7 = 36
36 + 6 = 43
70+9x+7-21x-5=0
-12x=-72
x=6
Explanation:
The three inner angles of the triangle add up to 180. And if a straight line is split into two angles, those also add to 180 degrees. So we can make the equation '9x+7 + 70 + 180-(21x+5) = 180'
Answer: no solution
