A class of 32 consists of students who either have red or yellow shirts if there are 12 more people with red shirts than there are people with yellow shirts how many of the students have red shirts

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
