What is the value of │x + 7│? (1) │x + 3│= 14 (2) (x + 2)2 = 169

I feel the answer should be E as in both the option we will get 2 different values of x.

Am I going wrong?

STAT1 |x+3| = 14 will give you two solutions x+3 = 14 and x+3 = -14 x = 11, -17 SO, NOT SUFFICIENT

STAT2 (x+2)^2 = 169 x+2 = +-13 x = -15, 11 So, NOT SUFFICIENT

If you take STAT1 and STAT2 together then there is only one value of x which satisfies both the Statements and is x=11 so, x=11 Hence, Answer will be C
