Question

How do you solve the inequality `-2k+12<30`?

Answer 1

`k> -9`

Explanation:

To solve you need to get the k by itself.
To do this we can start by subtracting 12 from both sides.

`-2k+12-12<30-12`
`-2k<18`

Now we need to divide by -2. BUT as this is an inequality the inequality sign needs to be flipped when you divide both sides by a negative number.

`(-2k)/(-2)>18/(-2)`
`k> -9`
