A class of 34 children has two more girls than triple the number of boys. How many girls are there in the class?

The number of boys = 8

The number of girls = 26

Let the number of boys = x

The number of girls = y

According to the question:

x + y = 34

y = 3x + 2

From x + y = 34, y = 34 - x.

So,

So, y = 34 - x= 34 - 8 = 26

Solving them we get: x = 8, y = 26.
