The easiest way to understand such problems is to use graphical methodMadiha :) said:can anyone please explain why only -0.5 is the answer ..

Draw two lines:
y=2-3x
y=|x-3|
You will find that they only intersect at one point: x=-0.5
And |x-3| > 2-3x for all values of x greater than 0.5
Buddy, I never said that there was no numerical method to solve the problem. I was just showing the OP what the answers actually meant!MukeshG93 said:zeebujha said:The easiest way to understand such problems is to use graphical methodMadiha :) said:can anyone please explain why only -0.5 is the answer ..

No, there is a numerical method. All you have to do is solve for the two answers and check the solution for both of them. One will not fit because the modulus will cancel the negative of one side and so only one solution can be taken.
