Question

Solve -2/3 x > 8 or -2/3 x < 4.

Answer 1

x>-12, x<-6

Answer 2

{x | -12 < x < -6}

{x | x < -12 or x > -6}

{x | x > -12 or x < -6}
these are the options

Answer 3

why are they in {} brackets?

I don't really understand the format given, but for the first situation -> -2/3x > 8, the answer is when x>-12, it fulfills the equation. As for the second, its x<-6.

It should be option 3?
