$8 y$ $8y$

Explanation:

Think of it as the $y$ $y$ 's being apples.

Starting with $- 1$ $-1$ apples, now add $3$ $3$ apples and you will have $- 1 + 3 = 2$ $-1+3=2$ apples. Take away $6$ $6$ from that and you'll have $2 - 6 = - 4$ $2-6=-4$ . Finally add $12$ $12$ and you got yourself $- 4 + 12 = 8$ $-4+12=8$ apples!
