X + 3x = 12 
(Or 4x=12)
the first x is the number of girls then the second x is the girls times 3, which is how many boys there are.

Answer:
   The line of reflection is at y = x+6.
Step-by-step explanation:
The perpendicular bisector of AA' is a line with slope 1 through the midpoint of AA', which is (-4, 2). In point-slope form, the equation is ...
   y = 1(x +4) +2
   y = x + 6 . . . . . . . line of reflection
