$n + (n + 5) = 19$ $n + (n+5) = 19$
Solving gives 7 boys and 12 girls.

First write an expression for the number of boys and
another for the number of girls.

Let the number of boys be $n$ $n$ .
The number of girls is $n+5" there are 5 more girls than boys"$

There are 19 students altogether.
(Boys + girls makes 19)

$n + (n+5) = 19$

#2n + 5 = 19)

$2n = 19-5$

$2n = 14$

n = 7.
