Finding the Number of Pencils

Ava is counting the number of pencils she has. She realizes that if she adds 8 more pencils, she will have a total of 20 pencils. To find out how many pencils she currently has, she can set up the equation:

$$ x + 8 = 20 $$

where $$ x $$ represents the number of pencils Ava has. What is the value of $$ x $$?
