Mainly, in the case of simple inequalities, you have to remember that when multiplying or dividing by a negative number, the direction of the inequality changes, for example, from greater-than to less-than or vice versa. Also, for more complicated inequalities, such as those that involve polynomials or absolute values, additional steps are required.
Solving inequalities and equations are the same because both have variables in the equation.
I dont know the answer
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
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.
It is a method of solving equations (or inequalities) using graphs rather than analytical methods.
It makes it allot less confusing. But, that is just my opinion.
equations have an = sign, inequalities do not
Just keep doing the same thing to both sides of the equation at every step.
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
