## Solving Inequalities

Solving inequalities is basically the same as solving an equation but you have a different symbol rather than the '='. For example:

Solve:

3y - 9 < 0

3y < 9

y < 3

Just think of the '</>' symbol as an '=' but don't change it because you may lose marks.

## Test Yourself

Solve these inequlities:

6k - 5 > 0

s^2 - 9 < 0

3x * 4 > 6

7m + 3 < 2

## Graphing Inequalities

You may also have to show your answer on a graph and it will ask you to shade in the area which the inequality is the same as.

Remember what the symbols mean:

5 < x (5 is less than x)

3 > y (3 is greater than y)

Simply draw the line to which your inequality equals and then shade in the correct area.
