Answer:

-2 > x > 8

Step-by-step explanation:

given that,

|2 x - 6| > 10

mod means the value will be positive when mod is solved.

it can be written as

± (2 x - 6) > 10

i) (2 x - 6) > 10

      2 x > 16

        x > 8

ii) -(2 x - 6) > 10

     -2 x +6 > 10

        - x > 2

           x < -2

hence , -2 > x > 8
