Final answer:
A root of the equation 2x – 8 = 12 is 10.
Step-by-step explanation:
To solve the equation 2x - 8 = 12, we can start by adding 8 to both sides of the equation to isolate the x term.
This gives us 2x = 20.
Next, we can divide both sides by 2 to solve for x.
This gives us x = 10.
Therefore, the root of the equation 2x - 8 = 12 is x = 10.
