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

The algebra math question takes up my limited energy and time, now I feel headache. Could someone help me to solve it with builder set notation?
Algebra math question: 12x-25>3x-5(x+6)http://www.bidanswer.com/Questions/QuestionInfo_10410.html

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.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
