Modulus (x) = 10

Modulus means we just take size of x neglecting the positive or negative sign.

But this how you solve modulus equation.

x = 10         This is the first part, which is the positive part.

Also for the negative part:

-x = 10        Divide both sides by -1. 

x = -10

So the solutions are 10 and -10.  (D)
