Section 6.3 Solve multi­step Inequalities I can solve inequalities using adding, subtracting, multiplying and dividing

Similar to "=" equations we solve by doing the same thing to both sides of the "<, <, >, >" inequalities. BUT remembering if we multiply or divide by a negative we flip the inequality.  

Multi­Step Checklist: (not all steps may be needed)* Simplify each side of the inequality    (distributive property and or combine like terms)* Move all variables terms to one side of the inequality    (adding/subtracting)* Move all constant terms (numbers without variables) to the other   side of the inequality (adding/subtracting)* Undo Multiplication/Division of the variable's coefficient    (Number attached to the variable)

Sep 7­5:46 AM

Important Recall with "=" equations we had "No Solutions" and "Infinite Solutions", the same is true for "<, <, >, >" inequalities

If when solving:      same "inequality sign" same then "infinite solutions"

ex)  2(x­5) > 2x ­ 10

NOTE:  graph of solutions looks like...

 If when solving:      inequality sign makes no sense then "no  solution"

ex)  3x+2 > 3x+15

NOTE:  graph of solutions looks like...

Ex)  Three less than the product of 6 and x is less than or equal to 21.

Ex)  Twice the sum of n and 7 is greater than the difference of n and 5. 

More homework Examples:  Translate the verbal phrase into an equality then solve the inequality.
