Ok, so how did you plug in? I an ignoring options (A) and (B) and focusing on just (C)

Option (C) {-4, 0, 1, 4, 5, 6}

|x-2|-|x-3|=|x-5|

You put x = -4. It didn't satisfy

You put x = 0. It didn't satisfy

You put x = 1. It didn't satisfy

You put x = 4. It satisfied

You put x = 5. It didn't satisfy

You put x = 6. It satisfied

How can you say there is no other value of x that satisfies this equation?

How can you say that all solutions of this equation are included in (C)?

Calm down. Dont get excited.

I meant I plugged in all the values in all the options (a,b,c,d and e)

Option C had two values that satisfy the equations and the other options didnt have two values. So I just went with C and got the correct answer. I did say I got lucky - maybe/maybe not.

"How can you say that all solutions of this equation are included in (C)"

lol Pretty ironic -

all solutions Precisely my point that the wordings of this problem can be easily misinterpreted. Just like you did mine.

The questions at the end 'How can you say...' were for you to mull over, not me pointing fingers. One could read them as 'How can one say ...'

Usually people stay detached and logical on this forum - they don't get excited/irritated so they stay productive.

I guess it's quite easy to misinterpret statements made online. For all the benefits online communication provides, this is certainly a folly it has.

And yes, one does need to read the question very closely to understand the meaning. The question is framed differently, not in the usual 'Which of the following represents all solutions of so and so...'

The word 'includes' helps. Which set "includes" all solutions. So all elements of the set may not be the solution but all solutions need to be in the set!
