(3x-2y-5)/5=(3x-5x+3y)/3
(4x-3y-2)/2=(3y-2x+3y)/3
5(3x-5x+3y)=3(3x-2y-5)
2(3y-2x+3y)=3(4x-3y-2)
-10x+15y=9x-6y-15
12y-4x=12x-9y-6
-19x+21y=-15 l(-1)
-16x+21y=-6
____________
3x / = 9 =>x=3
-19x+21y=-15 lx(-16)
-16+21y=-6 lx19
_____________
/ 63y = 126 =>y=2
Rescrie al doilea sistem, nu inteleg ce e acolo...
