Question

Cine ma ajuta vă rog dau coroana la ex 6,9,10

Answer 1

6).436-195=241

436=241+195

285+399=684

684-399=285

9). 365-279=86 zile ramase

10). e-ema, v-victor , d-daria

e+v+d=217(ecuatia 1)

e+v=158(ecuatia 2)

v+d=144(ecuatia 3)

cunosti e+v, inlocuiesti in ecuatia 1 pentru a afla d

158+d=217

d=217-158=59 (cu d aflat inlocuiesti in ecuatia 3 sa afli v)

v+59=144

v=144-59=85 ( acum ca stii v si d, inlocuiesti in prima sa afli e)

e+85+59=217

e+144=217

e=217-144=73

Answer 2

9) 365-279 = 86

10) E+V+D=217

E+V=158, atunci D=217-158=59

V+D=144, atunci E=217-144 = 73, iar V=144-D = 144-59 = 85

E=73

V=85

D=59, verificare 73+85+59=217  

6) 436-195 = 241, iar 241+195=436

285+399=684, iar 684-399=285
