There's an infinite number of equations we could make that equal 7, with the simplest being x=7. We can subtract 7 on both sides to get, x-7=0, multiply everything by 2 and it is 2x-14=0.

I have this suspicion that the full problem statement gave the student a list of equations to choose from, but the student omitted the list when posting the question. Otherwise it is, as you point out, an infinite solution set and it strikes me as a really odd question. :-)
