Talk:Algebra/Equations

Proposal for deltion
I propose that this page be merged with the solving equations page. Nfgdayton (talk) 17:18, 26 July 2010 (UTC)

The previous chapter Arithmetic has become quite long and this one, "Simple symbolic manipulation," is shorter. My suggestion is to cover the commutative, associative, distributive, and other fundamental laws of real numbers at the beginning of this chapter, especially since there are thoughts of covering a few extra topics (percentages, rounding, etc.) in "Arithmetic" as mentioned in comments at the bottom of its edit page. Also, it would be a good idea to introduce sets briefly and discuss solution sets to single-variable equations equations in this chapter.

There is a comment at the bottom of this chapter in the edit page about adding simultaneous equations to this chapter. It will become long enough as it is. I have started a new chapter on Simultaneous Equations in the second part of the book, "Equations and Functions." It comes right after the "Function Graphing" chapter, which I wrote. Therefore, simultaneous equations will be able to be discussed using graphs in the new chapter.

Incorrect expansion?
"3x − 2 > 2(x − 3). First, you may want to expand the right hand side: 3x − 2 > 2x − 6"

Quoted from the Solving Inequalities section of the article. Is that expansion true? What if x = 4, for example? That expansion assumed what, exactly, is applicable here?
