<U>1-st solution</U>


<pre>
From the condition, you have these two equations

g + b = 585,   (1)   (g = # of girls, b = # of boys)
g - b =  29.   (2)

Add these equations (both the left and the right sides). You will get

2g = 585 + 29 = 614.

Hence, g = {{{614/2}}} = 312.  The number of girls is 312.
Can you find yourself the number of boys?

<U>2-nd solution</U>


<pre>
Let g = the number of girls. 
Then the number of boys is g - 29, and the sum, which is the number of pupils, is g + (g-29).

So, you have an equation

g + (g-29) = 585.

Simplify and solve it for g:

2g - 29 = 585,

2g = 585 + 29 = 614,

g = {{{614/2}}} = 312.

There are 312 girls.

And how many boys?
