let the number of boys be 'x '
then the number of girls = 2x-3
if girls are 15 we have to find the number of boys
so ,
2x-3 = 15
2x = 15 +3
2x = 18
x = 9.
therefore number of boys = 9
then the number of girls = 2x-3
if girls are 15 we have to find the number of boys
so ,
2x-3 = 15
2x = 15 +3
2x = 18
x = 9.
therefore number of boys = 9
