Answer 3

To solve the equation ||x| + 2| = 7, we need to consider the absolute value of the expression inside the outermost absolute value symbols.

Let's break down the equation into two cases:

Case 1: (x + 2) is positive: In this case, we have |x + 2| = x + 2. Therefore, the equation becomes: x + 2 = 7

Solving for x: x = 7 - 2 x = 5

So, one solution in this case is x = 5.

Case 2: (x + 2) is negative: In this case, we have |x + 2| = -(x + 2). Therefore, the equation becomes: -(x + 2) = 7

Solving for x: x + 2 = -7

x = -7 - 2 x = -9

So, another solution in this case is x = -9.

Therefore, the solutions to the equation ||x| + 2| = 7 are x = 5 and x = -9.
