Final answer:
The value of x in the equation 2x - 4 = 8 is 6.
Step-by-step explanation:
To find the value of x in the equation 2x - 4 = 8, we can solve for x by isolating it on one side of the equation. We start by adding 4 to both sides:
2x - 4 + 4 = 8 + 4
2x = 12
Then, we divide both sides by 2 to solve for x:
2x/2 = 12/2
x = 6
So, the value of x is 6.
