B=brianne present age
c=camila present age
b=3c (brianne is three times as old as camila)
b+4=2(c+4) (four years from now she will be two times as old as Camila)
<span>b + 4 = 2c + 8
b = 2c + 8 - 4
b = 2c + 4
Replace b with 3c
3c = 2c + 4
3c - 2c = 4
c = 4
Camila is four years old.
b+4=2c+8
b=2(4)+4
b=8+4
b=12
Brianne is 12 years old. </span>
