The two equations I see are : 2x+7>-3 2×+7-10 2× -5 but < 1 So, the values that fit this are -4,-3,-2,-1,& 0 -5 & 1 would not work because of the phrase in the problem "in between"

7+2X =-3 and 7+2X = 9 2X = -10 and 2X = 2 X = -5 and X = 1 X = -5 to +1 The numbers in between are -4 to 0

Between - 3 and 9, so exlcusive - 3 and 9 ...

Haven't watched the video, but agree that the solution doesn't include the outer values of the set when "between" is in the question. My inequality looks like: -3

I conceive the problem slightly different than you, and therefore formulate a slightly different initial equation. I see the part in the middle as equal to or greater than -3, and equal to or less than 9. Including the end points of the range provides two additional solutions. By analogy, I conceive of three integers integers in the range between 1 and 3.

How does -4 fit between -3 and +9?

When you plug those numbers back in your result will be between -3 and 9. 2(-4)+7= -8+7= -1 which is between -3 and 9.

Problem specifies "between" which does not include. Therefore the equation is: -3

Find all k in the integers such that -3 < 2 * k + 7 < 9 is a sufficient way to phrase this. No wonder our kids are failing math when we use words like "seven more than twice an integer" and "between", which is needlessly ambiguous.

Why is -4 included when it is not in-between -3 & 9?

There is no definition of what the word "between" means in mathematics. I am a database programmer and in SQL, "between 3 and 5" means 3, 4 or 5, not just 4.

I remember learning that greater than and less than do not include, but greater than/equal to and less than/equal to do include. Perhaps SQL lacks the greater than/equal to and less than/equal to sign so the designers made a compromise.

Okay, 9 times an integer is betwwn -3 and 9. So that only works with the integer 0.

Did it in my head and had both -5 and 1 included. Then realized the question said BETWEEN -3 and 9.

No, -5 and 1 are NOT included. That's what the word BETWEEN means.

Being pedantic isn't cool, but a few others bug me as well (one from this video and one from many others), namely, linear instead of lunear and algebraic instead of algeberic. Still, let's not be picking at minor details any longer, okay?

I didn't hear any gaslighting, and--even if there was some gaslighting going on--people need to toughen up a bit and learn to not play victim, or make others out to be victimizers, at every chance they get.
