Hiii...first of all...am I right here?😳😆
 
I have to do certain Maths-exercises and I'm really having a big problem with this one here:
 
Appraise for each real number a every real numbers x, who complete the inequation

||x-1|+x-3|<a

I hope someone kinda knows what to do and might be able to explain it to me and help me to find the right solution. I know, that there's something with 2 cases, but...

Thanks.
And Happy Diwali! :)
