can someone help me with this please(: In the equation │x│ = -a where a is a positive integer, what can be said about the solution? How can you modify the value of a so that you would have a solution to │x│ = -a of ±a?

    this is what others have put │x│ = - (-a) X = - (-a) or x = + (-a) X = a or x = - a

    it can have solution only if \[\left| x \right|=a,if~a~ is~ positive \] \[\left| x \right|=-a ,if~a~is~negative.\]

    they have not made distinction between positive and negative quantity.
