It is important to know several techniques for solving equations and inequalities because one may work better than another in a particular situation.
it often simplifies arithmetic
The method is the same.
Study everything - that's your best bet. Important subjects probably include: Polynomials, Exponents, Radicals, Solving Equations, Solving Inequalities, Absolute Value Equations and Inequalities, Lines, Word Problems, Systems of Equations (2x2's), Factoring, Division of Polynomials, Quadratics, Parabolas, Complex Numbers, Algebraic Fractions, Functions
Just keep doing the same thing to both sides of the equation at every step.
Solving inequalities and equations are the same because both have variables in the equation.
Inequalities and equations are both the same because they are both mathematical expression and they both use the same steps EXCEPT for the end. Inequalities and equations are both different because equations have an equal sign, the answer is not an interval, and the answer is a specific answer. Not a range. While inequalities don't have an equal sign, its answer is an interval, and it's answer is in a range.

Bogomol'nyi-Prasad-Sommerfield bound is a series of inequalities for solutions. This set of inequalities is useful for solving for solution equations.
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
The method is the same.
It makes it allot less confusing. But, that is just my opinion.
Equations = the method
