Answer:
The value of x is 
.
Step-by-step explanation:
Given expression is:
We have to solve this for x.
First we will multiply both sides of the equation by 3
2(x-2) = 12x
2x-4=12x
Now we will be subtracting 2x from both sides of the equation
2x-2x-4=12x-2x
-4=10x
10x=-4
Dividing both sides by 10
Hence,
The value of x is .
