Explanation:

I'm going to use #Y# in place of the unknown variable.

#7+7 xx Y-5=79#

First, you will add the two sevens at the beginning together..

#14 xx Y-5=79#

Then, you will add five to the other side of the equation.

#14xxY=84#

Finally, you will divide both sides of the equation to get...

#Y=6#
