Answer: #color(brown)(7y+8)#

We group like terms and work out the final value for each group.

#color(blue)("Consider "7y)#

This is the only term in #y# so there is no work to be done on it!
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#color(blue)("Consider the integer values of 16 and 8")#

When grouped we have: + 16 and -8. Notice that their signs follow them!

As a whole this is: 16-8 which after the subtraction becomes +8

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#color(blue)("Putting at all together we have: " 7y+8)#
