Three friends divided some bullets equally
⇒ total bullets = 3x
.........................................................................................................
They each shot 4 bullets
⇒ total bullets shot = 3 x 4 = 12
⇒ bullets remain = 3x - 12
.........................................................................................................
Remaining bullets is equal to what each had when divided:
⇒ 3x - 12 = x
⇒ 2x = 12
⇒ x = 6

Find original number of bullets
