Answer:
x=6
Explanation:
First you want to distribute the problems to it will turn into 2x-12=4x-24. Then you want to add 12 to both sides to cancel it out.
2x=4x-12
Now you add 4x to the side with 2x which makes the 4x negative.
2x-4x=12
2x-4x=-2x
-2x=-12
divide -2 on both sides to get
x=6
There is only one answer x=6
