You can put this solution on YOUR website!
Let b=number of boys
g=number of girls
The equations are:
b=5g
b=100-15g
Since both equations are equal to b,they are equal to each other:
5g=100-15g
Now solve the equation
20g=100
g=5
Substitue the number of girls in one of the original equations
b=5(5)
b=25
There were 5 girls at the party and 25 boys at the party
