Start with an empty box of instead of x. I have found that an empty box transfers to them the concept of placeholder that needs to be filled. it can transition to a x later

You can also compare to words like it, thing, she, he, and equations to definite descriptions.

"I don't know who she is."

"The culprit was wearing a red coat."

"The mystery number plus 3 is equal to 5."

"I'm thinking of a number, but I'm not going to tell you what it is. But I will tell you that if I multiply it by 3, and then subtract 5, I get 1."
