-3;3;0 absolute value doesn't affect value of x, just it's evolution so yes, in bracket of absolute value can be negative number, only it changes minus to plus after you start working with it

but if u delete the abs signs before solving it's 3;0 only

why would you delete it? 1. solve inner bracket = value of x is possitive 2. 2 times x minus 3; = 2 X x - 3 3. abs value makes 2 X x - 3 to become or to stay possitive 4. value from step 3. is equal to 3
2020-11-24 12:26
the outcome will always be >=0 with that |x|

wtf is this? Is it 2mod*xmod*-3mod = 3 ? Please send a photo of the question or write it properly i dont get it. Wait a min, is it, 2mod*xmod + (-3mod) = 3?

I initially thought it was |2|*|-3| = 3 XD

You should have written it as |(2|x|-3)| or atleast | 2*|x| -3|

Is it |2x-3|= 3 or |2|x |-3| =3 ? Its really a difference because if you had one mod it will be x € (0,3) but if not you just divide the mods and x = 3

oh ez question then (2IxI - 3) = 3 or -3 if we say (2IxI - 3) =3, then 2lxl= 6, which means x=3 or -3 if we say (2IxI - 3) = -3, then 2IxI= 0, which means x=0 x=0,3,-3

exactly
2020-11-24 13:26
yeah this is basic math 2|x|-3=+-3 take + 2|x|=6 |x|=3, x=+-3
2020-11-24 13:24
|x| = x if x>=0 |x| = -x if x<0 |x| is always positive. Also no idea what your question is? How you wrote the equation isn't correct... I'm gonna assume you wrote 2*x*|-3| = 3 <=> 6*x=3 <=> x = 3 / 6 <=> x = 1/2
2020-11-24 13:28
lets say x>=0 |2x-3| = 3 2x-3 = +- 3 case a) 2x-3 = 3 2x = 6 x= 3 (x should be greater than or equal to zero, acceptable answer) case b) 2x-3 = -3 2x = 0 x = 0 (acceptable answer since x>=0) lets say x<0 |2*(-1)x-3| = 3 -2x-3 = +-3 case a) -2x-3 = 3 -2x = 6 x = -3 (acceptable since x<0) case b) -2x -3 = -3 2x = 0 x = 0 (not acceptable since x<0) So final answer is x can be 3,0,-3
