102 - lalele
a = r : 5=> r = 5 x a
a + r = 102
a + 5 x a = 102
6 x a = 102
a = 102 : 6
a = 17
r = 5 x 17
r = 85
a = r : 5=> r = 5 x a
a + r = 102
a + 5 x a = 102
6 x a = 102
a = 102 : 6
a = 17
r = 5 x 17
r = 85
102 sunt in total lalele
a = r : 5=> r = 5 x a nr,lalelelor albe,si nr lalelelor rosii
a + r = 102 albe+rosii
a + 5 x a = 102
6 x a = 102
a = 102 : 6
a = 17
r = 5 x 17
r = 85
a = r : 5=> r = 5 x a nr,lalelelor albe,si nr lalelelor rosii
a + r = 102 albe+rosii
a + 5 x a = 102
6 x a = 102
a = 102 : 6
a = 17
r = 5 x 17
r = 85
