Answer:

#x-2<=6#

#x<=8#

Explanation:

A sum is the result of addition.

The sum of a number and #-2# means the addition of a variable (to represent the number), which I'll call #x#, and #-2#:

#x+(-2)=x-2#.

No more than #6# means the sum is equal to or less than #6#.

#x-2<=6#

Solution

Add #2# to both sides.

#x<=6+2#

#x<=8#
