unit 6.5 - solving linear inequalities by using multiplication and division
what we need to know
more information
When solving inequalities by adding and subtracting, remember:
1. remember: To solve multiplication and division equations
2. solving two-step linear inequalities using multiplication and division
put simply (make sure you remember this):
LOOk at this example:
look at what its meant by "multiplying by a negative number", and notice how the inequality symbol is reversed:
look at what its meant by "dividing by a negative number", and notice how the inequality symbol is reversed:
3. summarizing with some more examples
look at some more examples
4. If you wonder why the inequality sign is reversed when multiplying or dividing by negative numbers, here is the reason.
Understand this, but no worries: you do not need to memorize it as is.
