x = total amount of students in 8th Grade.
we know only one-thrid of the class went, so (1/3)x or x/3 went.
we also know 5 coaches went too, and that the total amount of that is 41.

now, to verify, well, what do you get for (108/3) + 5?
X= 4y+4/3yz this is they solution
2+2736=2738*2484848/484848=14032.26129
5 multiplied by .3 is 1.5
1.5 + 18.5 = 20.
y = 9.25
