for x<4
|x-4| = -x+4 = a
x = 4-a
for x>4
|x-4| = x-4 = a
x = 4+a.
|x-4| = -x+4 = a
x = 4-a
for x>4
|x-4| = x-4 = a
x = 4+a.

*thankyou
a is constant
if you vary a then the value of x varies
but every a has two values of x
it depends on x not a
a can be +ve -ve or zero. So x depends on it
hope u understand now.
yes, now its ryt
Okay thankyou.
but in question a is constant so don't confuse urself
