(4) x=2 or x=4 are the two solutions given
We are given with two values for x , so we cannot choose an inequality
General form of absolute value equation is
|ax + b| = c
where c is the distance between the middle of the given solution and the end of the solution
x=2 or x=4
middle of 2 and 4 is 3
Distance between 3 and 4 is 1 . so c=1
Hence c is positive. so option B is correct
(5) For all absolute value , there will be two solutions
|ax + b| = c, when c is positive then there is 2 solutions.
When c is 0 then there will be only one solution
So answer is 1 or 2 solutions
