This activity is about solving two inequalities.
Example
Solve the inequalities:
x ≥ -12 and 2x + 6 ≤ -6
Answer
To solve 2x + 6 ≤ -6
First of all, we subtract 6 from both sides to get:
2x ≤ -12
Then we divide both sides by 2 to get:
x ≤ -6
The other inequality x ≥ -12 is the same as saying -12 ≤ x
Putting the two solutions together we get:
-12 ≤ x ≤ -6
Let's have a go at some questions now.
