A total of 56 children went on a trip to the pupils of the two fourth grades. That 4A was four pupils more than 4. B How many pupils from each class went on a trip?

Correct answer:

a =  30
b =  26

Step-by-step explanation:


a+b=56
a = 4+b

a+b = 56
a-b = 4

Row 2 - Row 1 → Row 2
a+b = 56
-2b = -52


b = -52/-2 = 26
a = 56-b = 56-26 = 30

a = 30
b = 26
