the answer to your question is x=49

commas, dashes, or parentheses
Nonessential appositive phrases can be separated from the rest of a sentence in three ways—with commas, with dashes, or with parentheses. Let’s look at example sentences that essentially mean the same thing:
The best pet in the world, a dog, will always be known as “man’s best friend.”
The best pet in the world—a dog—will always be known as “man’s best friend.”
The best pet in the world (a dog) will always be known as “man’s best friend.”
