Step-by-step explanation:

let's simply try and solve this, and see where we end up.

x/2 = x/3 - 12

just by looking at it : we are comparing seemingly something larger (x/2) with something smaller (x/3), and we subtract even something more from the smaller number (- 12).

this looks therefore like a negative solution.

let's try to get rid of the fractions.

first we multiply everything by 2 :

x = 2x/3 - 24

then we multiply everything by 3 :

3x = 2x - 72

x = -72

aha ! we were right.

so, the solution set is {-72}.

and yes, by the way, this is a real number. but the solution contains only one number. so, the answer option with general x as all real numbers is wrong.
