  • No, the domain should be x<3/4. Because of the way I solved, adding 4x to both sides first, I divided by 4, not -4 so I did not need to flip the inequality.

  • @xxxaliendudexxx2 ...but after pausing and rewinding a few times, it actually does help. Thank you! :)

  • too fast for me :\

  • When you divided by 4 at 2:09 doesn't that change the direction of the inequality? It's suppose to be 3/4 < x?

  • Thank you!
