Please help me with this question...

What is the value of y?

(1) 3|x^2 - 4| = y - 2

(2) |3 - y| = 11

My approach:

Statement 1: Insuff as there are 2 variables
Statement 2: Insuff

3-y = 11, 3 - y = -11
=> y = -8, 14

Both: Substituting values of y from statement no. 2 into statement no. 1 doesnt help to solve for y. Hence my answer is E, however the correct answer is C.

Please help,

Thanks in advance,

y=2+3|x^2 - 4|= always a +ve value, regardless of x = +ve or -ve.

NOT SUFFICIENT

(2) |3 - y| = 11

y=-8 if y is +ve
y=14 if y is -ve

NOT SUFFICIENT

1)+2) y is +ve so y=-8.
SUFFICIENT
C
