Răspuns:
cu banii de pe doua orhidee se pot cumpara 44 de lalele
Explicație pas cu pas:
3o=5c =) 3o=11t+1c=) 3o=1t+48l+1c
4c=11t =) 4c=1t+48l =)1t=-48l+4c
5t=24l =) 5(4c-48l)=24l =)20c-240l=24l =)20c=240l+24l =)20c=264l
?l=2o
3o=5c /*4 =)12o=20c =)12o=264l
12o-------------------------264l
2o-----------------------x? x=lalele
[tex]x=\frac{264*2}{12} =\frac{132*2}{6} =\frac{66*2}{3} =\frac{22*2}{1} =44[/tex]
2o------------------------44l
