Are you sure you transcribed the question correctly?alexandrabiorka wrote:If y = -z, where z is a prime number, what is the value of x?

2.) y > -8
There's a problem with statement 1.
|x + 2| is greater than or equal to zero (that's the nature of absolute values)
So, |x + 2| + 2 is greater than or equal to 2
In other words, |x + 2| + 2 is POSITIVE
If y = |x + 2| + 2, then y is POSITIVE
HOWEVER, we're told that y = -z, where z is a prime number
Since all primes are positive, this means that z is positive.
Since y = -z, we can conclude that y is NEGATIVE
Obviously y cannot be both positive and negative.
Cheers,

Given : y = -z, where z is a prime number i.e. y = -2 or -3 or -5 etc...
Statement 1) |x+2| + 2 = y
But |x+2| + 2 Must be positive
and as per question y must be negative Integer as Z is a Prime Number and y = -z
This seems Incorrect set of information...
Please check if the information is appropriate...
