    hello guys: for time stamp 22:48 - 23:25 , thus for x = -9, on the right hand side, its supposed to be 2(-9)+5 = -13. All the same, the answer obtained satisfy the inequality since x was chosen to be smaller that -8. Kindly take notice of that when watching the video and make the correction. The correction is what i have done above - 2(-9)+5 = -132(-9)+5 = -13 (on the right hand side). Meanwhile the final answer is correct. Thanks for watching. Continue to support SKA.

    Please for question 12 at x equals -9, why is it that for x-3 you substituted -9 but for the right hand side you substituted -12

    What happens when there is a value that doesn’t satisfy the inequality?

      Can you be more specific?. Moreover there are a few properties which may have not been outline in my video. If your question doesn't fit, you may want to search online for a relating property.

    You made a mistake with the latter part of the inequality for |x-3|≥2x +5
    When you said x=-9

      Yes, ive noticed that, insteadd of -9 i used -12, thanks tor the correction... But anyways |-12| is greater or equal to the RHS. But thanks for the correction
