Answer:

part a :

8n-10 + n+4 = 2n+3 + 3(2n-1)

part b :

n = 6

baseball = 38

flag football = 15

kickball = 10

soccer = 33

Step-by-step explanation:

part a :

8n-10 + n+4 = 2n+3 + 3(2n-1)

part b :

9n - 6 = 2n+3 + 6n-3

9n - 6 = 8n

n = 6

now plug in to every equation to solve for how many student play in that sport

baseball : 8(6)-10 = 38

flag football : 2(6)+3 = 15

kickball : (6)+4 = 10

soccer : 3[2(6)-1]=33
