there are 124 students in the band. there are 12 more boys than girls in the band. how many boys and how many girls are in the band.

Respuesta :

bcalle
b = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12

g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56

b= 56 + 12
b= 68
