|-2x+3|=|2x-3|
atuinci ecuatia devine
|2x-3|=7
adica 2x-3=7 pt x>3/2 rezolvand obtinem x=5>3/2 deci buna
si 2x-3=-7 ptx<3/2 rezolvand obtinem x=-2<3/2 careverifica si aceasta
S={-2;5}
verificare |-4-3|=|-7|=7 adevarat
|10-3|=|7|=7 adevarat
exercitiul este bine rezolvat
OBs. Nu am auzit pana acum de "solutia potrivita"
