Simultaneous equations can also be solved by substitution or graphically

It is important to know several techniques for solving equations and inequalities because one may work better than another in a particular situation.
One important difference between solving equations and solving inequalities is that when you multiply or divide by a negative number, then the direction of the inequality must be reversed, i.e. "less than" becomes "greater than", and "less than or equal to" becomes "greater than or equal to".Actually, from a purist's sense, the reversal rule also applies with equations. Its just that the reversal of "equals" is still "equals". The same goes for "not equal to".
The method is the same.
It really is utilized to solve specific variablesIt really is utilized to rearrange the word.

Presumably you'll arrive at the wrong solution.
Yes, but only if you know exactly what you are doing.
Rene' Descartes is credited with founding rational root theorem. He also created the rules of signs to be used with solving equations.
Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.

They are actually to the one half power. You can take a factor in the radical and sqrt it and put in on the outside... Ex. sqrt(28) = sqrt(4 * 7) = sqrt(22 * 7) = 2sqrt(7) sqrt(28) = 2 * sqrt(7)
Solving inequalities and equations are the same because both have variables in the equation.
Yes. Trigonometric identities are extremely important when solving calculus equations, especially while integrating.
