Answer 3

To solve the equation ||х|| - 1 = 3, we need to consider two cases based on the absolute value:

Case 1: х is positive or zero (х >= 0). In this case, the absolute value of х is equal to х, so we can write the equation as:

х - 1 = 3

Now, let's solve for х:

х = 3 + 1 х = 4

So, one solution for х is х = 4.

Case 2: х is negative (х < 0). In this case, the absolute value of х is the negation of х (i.e., |х| = -х), so we can write the equation as:

-х - 1 = 3

Now, let's solve for х:

-х = 3 + 1 -х = 4

Divide both sides by -1 (remember to flip the inequality when dividing by a negative number):

х = -4

So, another solution for х is х = -4.

Therefore, the solutions to the equation ||х|| - 1 = 3 are х = 4 and х = -4.
