To find the domain, we need to solve for x since y can take any value.

4y - 2x = 20 
2x = 4y - 20 
x = 2y - 10

Now we can see that x is a linear function in terms of y, which means it will continue indefinitely in both directions. Therefore, the domain is all real numbers, which is represented by choice B.
