When solving a linear inequality, treat it just like you were solving an equation with a few exceptions when you multiply or divide both sides of an inequality by a negative constant, change the sense (direction) of the inequality when both sides of an inequality are the same sign, change the . Are you having difficulty understanding inequalities these simple, easy to understand examples will guide you through all steps of understanding and solving inequality problems. Inequalities solving inequalities is not so different from solving regular equations in fact, an inequality sign (,≤,≥) is treated the same as an equal (=) sign when solving inequalities involving only addition or subtraction.

Page 1 of 2 16 solving linear inequalities 41 solving linear inequalities solving simple inequalities inequalities have properties that are similar to those of equations, but the properties.
Equations and inequalities involving signed numbers in chapter 2 we established rules for solving equations using the numbers of arithmetic now that we have learned the operations on signed numbers, we will use those same rules to solve equations that involve negative numbers. Solving inequalities date_____ period____ solve each inequality and graph its solution solve each inequality and graph its solution 1) 0 3 x − 3 − 6 −2 . Solving inequalities - practice / review: this is a great activity for practicing one-step and multi-step inequalities students put together matches from cut up . Solving inequalities mc-ty-inequalities-2009-1 inequalities are mathematical expressions involving the symbols , solve’ an.
An inequality such as 3x - 7 8 is similar to the equation 3x - 7 = 8 however, this time we are looking for numbers which if you multiply by 3, then subtract 7, you get an answer of less than 8 . Introduction to inequalities inequality tells us about the relative size of two values mathematics is not always about equals, sometimes we only know that something is greater or less than. To solve a compound inequality, first separate it into two inequalities determine whether the answer should be a union of sets (or) or an intersection of sets (and) then, solve both inequalities and graph if it is unclear whether the inequality is a union of sets or an intersection of sets . In this chapter we will look at one of the most important topics of the class the ability to solve equations and inequalities is vital to surviving this class and many of the later math classes you might take.
Solving inequalities - detailed examples and practice problems help make these lessons easier to understand. Most of the rules or techniques involved in solving multi-step equations should easily translate to solving inequalities the only big difference is how the inequality symbol switches direction when a negative number is multiplied or divided to both sides.
