Solving Polynomials

It does get a bit confusing when you have the same variable on both sides of the
equals sign, doesn't it? We know that when the problemis solved, it will look
like "k = something". So we have to try to get all the "k's" on one side of the equation, and all the "somethings" on the other, and then we'll be done!

The first step is to do all the multiplication and addition and subtraction on each side of the equals sign by itself. That way we get rid of the parentheses.

10 - (k+5) = 3(k+2)

On the left side, we have 10 minus (k plus 5). The parentheses mean we have to subtract BOTH k and 5 from 10. Okay. So we can rewrite it without the parentheses and the left side becomes:

10 - k - 5

And because addition and subtraction without parentheses can be done in ...

This solution assists in solving this problem: 10-(k+5) = 3(k+2).
