Answer:

22 kids

Step-by-step explanation:

R (red shirts)

Y (yellow shirts)

R= Y+12 (to make them equal, you need to add 12 to the yellow because it tells you that there are 12 more red shirts than yellow)

R+Y=32 (the amount of students in the class)

Substitute R from the first equation into the second one.

(Y+12) + Y = 32

2Y +12 =32 (subtract 12 from both sides)

2Y =20  (divide by 2 on both sides)

Y=10

Now you know the amount of kids wearing yellow shirts.

Subtract the whole class and the yellow shirts.

32-10= 22
