Answer:
10/3 or 3.33333333...
Explanation:
In order to find x, you must isolate it on one side. To do this, add 24 to both sides to cancel out the "-24" on the side with x on it. This gives you 12x=40. Now, divide 40 by 12 to cancel out the "12" attatched to the x. This will give you 3.333333... or 10/3.
