Question 932417
x = # of girls, y = # of boys


-------------------------------------------------------


x+y = 50


y = 50-x


-------------------------------------------------------


3/2 = x/y


3/2 = x/(50-x)


3(50-x) = 2x


150 - 3x = 2x


150 = 2x+3x


150 = 5x


5x = 150


x = 150/5


x = 30


-------------------------------------------------------


y = 50 - x


y = 50 - 30


y = 20


-------------------------------------------------------


There are 20 boys
