There are 4 more girls in mrs pitt's class than mr browns class. five girls moved from mrs pitt's class to mr browns class. now there are twice as many girls in mr browns class as there are in mrs pitt's. how many girls were in mr brown's class to begin with?

The number of girls in Mr Brown's Class were:

                       7

Step-by-step explanation:

Let the number of girls in Mr. Browns Class be 'x'

Then the number of girls in Mrs Pitt's Class are: x+4

( Since,it is given that:

there are 4 more girls in Mrs Pitt's class than Mr browns class )

Now,  five girls moved from Mrs Pitt's class to Mr browns class.

This means that now,

The number of girls in Mr Browns class are: x+5

and Number of girls in Mrs Pitts class are: x-1

( Since, x+4-5=x-1)

Now, as we are given that:

There are twice as many girls in Mr browns class as there are in Mrs Pitt's this means that:

x+5=2(x-1)

x+5=2x-2

2x-x=5+2

x=7

Hence, the number of girls in Mr Brown's Class were:

7 girls.
