This man is a genius. I've been trying to figure this out for two years and in 5 minutes he explained to me what nobody else could. Wow.

How about this one which was given to my son (nearly 13) to figure out: -3(q-z) - r = tz , solve for z.

so get rid of the brackets, so I write:
-3q + 3z - r = tz

I then divided with t on both sides.

Couldn't get any further.

Seriously, what is the point of this? What bearing does this have on my daily life? With regard to the type of mathematics that most people will meet in the workplace, is solving literal equations even relevant? How many people will even care?

I think you should focus on advanced math because not many people are searching for easy things like this, it’s usually harder things like pre cal, calc etc
