another hard math question to me have to do with inequalities?

subtract 11 from both sides and get

-2x>-26

divide by negative 2 on each side

x and 13

dividing by a - means you flip the sign

x<13

Do it just like a normal equation.

-2x + 11 > -15

=> -2x > -26

=> 2x < 26 [the difference is when you multiply or divide by a negative --- the symbol reverses]

=> x < 13

:)

-2x+11>-15

-2x>-15-11

-2x>-26 /:-2

x<13 (when dividing with negative, the inequality sign turns)

Swing the 11 over:

-2x >-26

Throw the -2 over, switch the pac man:

x<13

i individually don't comprehend why you're beating your self up. you would be shocked how many human beings won't be able to get this question without drawing a diagram to instruct them a thank you to do it and that they might laboriously visit fifteen formerly they even suspected that there advance right into a trend. Math isn't organic to us and it fairly is something yet intuitive. it fairly is at the beginning a language, yet even that's no longer significant. what's critical is that it fairly is amazingly precis even although there are literally hundreds of "genuine existence" examples. in case you do no longer have faith me attempt including or subtracting the way the Romans did it. it fairly is a nightmare. An abacus is as no longer consumer-friendly to apply as pencil and paper arithmetic. Their language for counting advance into centuries previous to those around them in spite of the undeniable fact that it continues to be very very awkward. i will basically say to you that each physique (inclusive of Einstein) hit a brick wall while handling arithmetic. ultimately each physique hits their point of incompetence. All i will advise to you is which you maintain at it. do no longer enable frustration supply up you from going greater. instead, rejoice which you acquire a formula to your 28 meters. Your glass is a million/2 comprehensive, no longer a million/2 empty. consistently think of that way.

-2x+11>-15

-11 -11

-----------------

-2x/-2>-26/-2

The sign is switched because you divided by a negative number

x<13
