The answer is x < 12
1) Minus 6 from both sides of the inequality
2) Multiply both sizes by 4
3) Divide both sides by -3
4) Swap the direction of the inequality (You always do this when you multiply/divide both sizes of an inequality)
5) You should have x < 12
The frequency stays the same and the wavelength decreases.
