Need help about the solution of an algebra math question with builder

Re: Need help about the solution of an algebra math question with builder

I will solve, you will put it into set notation.

Add 25 to both sides.

Add 2x to both sides.

Divide by 14.

Please finish up from there, or show some work indicating where you need help.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
