Replace all the variables that we know the value for.

-3 = |x|

Make to equations from this one.

-3 = x and - 3 = - (x)

Solve the first one.

-3 = x

x = - 3 < - - Switch it around

-3 = - (x)

- (x) = - 3 < - - Switch it around

x = 3 < - - Divide both sides by - 1

So, there are two possible answers, - 3 and 3.
