Question

solution of |3-x| = x-3 is???

Answer 1

This Q is based on concept of modulus .
first of all break modulus.

when, x >3 then,

-(3 - x) = x - 3

-3 + x = x - 3

- 3 = -3
hence , x > 3 for all real value .

when , x≤ 3 then,

(3 - x) = x -3

2x = 6

x = 3

hence, x = 3 is one of solution this case.

now,
solution is
x € { 3 } U ( 3 , ∞)
