Ashley has a lot of friends she gave lollipops too, $18$ $18$ friends to be exact.

Explanation:

The formula for this problem can be written as:

$40 - 2 f = 4$ $40 - 2f = 4$ Where $40$ $40$ is the number of lollipops Ashley originally had; $f$ $f$ is the number of friends Ashley gave $2$ $2$ lollipops each to and $4$ $4$ is the number of lollipops remaining.

Solving for $f$ $f$ while keeping the equation balanced gives the solution:

$40 - 2 f - 40 = 4 - 40$ $40 - 2f - 40 = 4 - 40$

$0 - 2 f = - 36$ $0 - 2f = -36$

$- 2 f = - 36$ $-2f = -36$

$\frac{- 2 f}{- 2} = \frac{- 36}{- 2}$ $(-2f)/-2 = (-36)/-2$

$1 f = 18$ $1f = 18$

$f = 18$ $f = 18$
