Answer 2

im confused it is asking for two answers

Answer 3

If there is positive digit in the the bracket & if there is negative the answer will come as negative . now, we don't that the digit in the bracket is negative or positive . so, the answer will come as both positive or negative.i.e
6 & -6.

Answer 4

THANKS

Answer 5

The other answer isn't -6. Here's why


|2x + 2| = 14

|2(-6) + 2| = 14

|-12+2| = 14

|-10| = 14

10 = 14 ... which is false


So x = -6 isn't a solution
