In a school there are 732 girls and 761 boys. 682 more girls and 8 more boys joined the school. How many girls are there in the school now?
There are $732$ girls and $761$ boys in the school. 

$x$ more girls join the school. 

$y$ more boys join the school. 

There are $732 + x$ girls and $761 + y$ boys in the school. 

$682$ more girls join the school. 

$8$ more boys join the school. 

$732 + x + 682 = 732 + x + y + 8$

$x + y = 8$

$x = 8 - y$

$732 + x + 682 = 1414$

$732 + (8 - y) + 682 = 1414$

$1414 - y = 1414$

$y = 0$

$x = 8$

There are $732 + 8 = 740$ girls in the school now.
