Answer:

The outside temperature is #75.6°#

Explanation:

Before you write an equation, you must define the variable. It is usually what you are asked to find.

Let the outside temperature be #x#.
Then decide what operation(s) to do

The dry ice temperature is lower than the outside temperature by #184.9°# This can be shown by a subtraction.

#x-184.9 = -109.3" "larr# now solve for #x#

#x-184.9 +184.9= -109.3+184.9" "#add 184.9 to each side

#x = 75.6°#
