#8n-5=7#

#n=3/2# or #1 1/2#

Explanation:

A difference is the result of subtraction, "times" means to multiply. This gives us:

#8n-5#, where #n# is the number.

"Equals 7" means to set #8n-5# equal to #7#.

#8n-5=7#

We can solve this equation to determine #n#.

Add #5# to both sides.

#8n=7+5#

#8n=12#

Divide both sides by #8#.

#n=12/8#

Simplify.

#n=3/2# or #1 1/2#
