There are 33 students in the band. There are 6 more fifth-grade students than third-grade students. There are an equal number of third- and fourth-grade students. How many third-grade students are in the band?

1. Zack

5th graders = x + 6 (this is because there are 6 MORE 5th graders than 3rd grade)

Make an equation
x + x + (x + 6)= 33
group like terms
3x + 6 = 33
subtract 6 from both sides to get x alone
3x = 27
divide both sides by 3
x = 9
PLUG IN 9 for x

5th graders = x + 6

add them to double check. Good luck

3. Alexa

Assuming that there is no other grades in the band

33 = x+(x+6)+x
33 equals the sum of all the parts

33 = 3x +6
Bring together like terms

27 = 3x
Solve for x

x = 9

There are nine third graders in the band
