Answer:

#16 - 3y#

Explanation:

Look at the parts individually, there is #10#, #-(2y - 6)# and #-y#. Breaking this down can help.

Looking at #-(2y - 6)#:

You multiply everything inside the bracket by #-1#. It may only look like #-# but there is a #1# there. Just like #y# is actually #1y#.

#-1 " x " 2y = -2y#
#-1 " x "-6 = 6 # (#- " x " - = +#)

So now we have,
#10 - 2y + 6 - y#

This can be simplified,

#10 + 6 = 16#
#-2y - y = -3y#

Therefore, it is simplified to just:
#16 - 3y#
