Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").

Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
its not much different besides the fact it has a '<' or a '>' insted of a '='. and you have to add/subtract/etc. a little diffrent.
When solving an equation, you are looking for a specific answer or answers. However, when solving inequalities, you are only looking for what an answer could be (for example, your answer could be less than 5 or greater than 32).
It is called solving by elimination.
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
