Lesson 5.3:
*Solving multi­step inequalities can be done in the same way that you
solve multi­step equations.
**Simplify (distribute or combine like terms)...then undo the
adding/subtracting before undoing the multiplication/division.
***Don't forget­­>When you multiply/divide by a negative
number...flip the inequality!!
****IF an inequality results in a "False" statement...the
solution is the empty set [ ]
IF an inequality results in all values working...the solution
is "All real numbers"
