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)

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) 1 (3x + 6) > 1 3
Ex) 2x 5 < 12
Homework Examples: Solve the inequality (variables on one side)

Ex) 5n < 2(n6)
Ex) 17c+9 < 8c2
Homework Examples: Solve the inequality (variables on both sides)

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.
