Let the no of stamps with Bella=x
Stamps with desire =5+x
Stamps with Javon=3(5+x)
=15+3x
Total no of stamps=200
So;
200=x+5+x+15+3x
200=5x+20
200-20=5x
180/5=x
x=36
Therefore;
The no of stamps with Bella =36
No of stamps with desire=5+36
=41
No of stamps with javon=15+3(36)
=123
Verification;
36+41+123=200
