Question

Rezolvati ecuatia x-6/3 - 3-x/2=-1,x apartine Z

Answer 1

Aduci la acelasi numitor adica inmultesti prima fractie cu 2 si a doua cu 3 si o sa ai 2x-12-9+3x/6 =-1 Inmultesti pe diagonala si faci operatiile din fosta fractie si iti da 5x-21=-1 => x=3

Answer 2

[tex]x-\frac{6}{3}-3- \frac{x}{2} =-1 \\ x-2-3- \frac{x}{2}=-1 \\ x-5- \frac{x}{2}=-1 |*2\\ 2x-10-x=-2 \\ x=-2+10 \\ x=8 \\ \\ \frac{x-6}{3}- \frac{3-x}{2}=-1|*6 \\ \frac{6(x-6)}{3}- \frac{6(3-x)}{2}=-1*6 \\ 2(x-6) -3(3-x)=-6 \\ 2x-12-9+3x=-6 \\ 2x+3x=-6+12+9 \\ 5x=15=\ \textgreater \ x=15:5 \\ x=3[/tex]
