Thanks for the video. Almost solved but forgot about those W functions 😉

X=4
2^x+x = 20
2^x+x-20=0
20 = 2^4 + 4
So, x = 4

"I consider it" is not a common English phrase, and this guy uses it every few seconds. And his usage is not even correct. Please find another phrase. How about "here we have" or better yet, just say nothing where you would use "I consider it."

When you have nothing good to say, just say nothing at all. Nothing grammatically or semantically wrong with his phraseology. The video's about math, however. Try no to foul the player if you can't play football.

@@unatwomey7112 Totally agree. It’s not how you say something, it’s what you say that is the most important.
