\(\displaystyle \frac {3x}{2x}\) can simplify into \(\displaystyle 1\frac{1}{2}\)

\(\displaystyle \frac{3+(2x)}{2x}\) <------ can't simplify

\(\displaystyle \frac{3x}{2+x}\) <---- can't simplify

my brain just farted for the 10th time. thx in advance
 
"thx in advance" for what? What is your question, or do you have one?

P.S. What if x=0 in \(\displaystyle \frac{3x}{2x}\)?

Furthermore...if x=3/4, \(\displaystyle \frac{3+2x}{2x}=\frac{3+\rlap{//}2x}{\rlap{//}2x}=3\). Why is that wrong? (and it is wrong!)

anything divided by 0 would be undefined

It is wrong because the numerator have +3. You'll be able to do that if you change the plus sign with multiplication sign.
