The equation seems to equal 72.
24/72+45/72=69/72
6 + 4 + 12 + 18 + 72 + 1 + 2 + 3 + 8 + 9 + 24 + 47 = 206
If 4a+24=72 then you start out by subtracting 24 from both sides because what you do to one side of the equation you must do to the other. That means that 4a+24-24=72-24. So 4a=48. Now you divide both sides by 4 and you get a=12.
