y1 = -2
y2 = 14

Explanation:

First of all separate the two absolute equations as if they were two separate equations (one positive and one negative)

6-y=8
6-y=-8

Then, you solve equations. Solve the first one

y=86y=2y=2

Then, the second one :

y=86y=14y=14

So the two solutions are

y1=2
and
y2=14
