a+b=610
a:b=4,10
a=4b+10
4b+10+b=610
5b=610-10
5b=600
b=600:5
b=120
a+120=610
a=610-120
a=490
a:b=4,10

a.I____I
b.I____I____I____I____I10I
Suma este 610 deci aflam suma partilor egale :
610-10=600
600:5=120 (a)
120x4+10=490 (b)
b.I____I____I____I____I10I
Suma este 610 deci aflam suma partilor egale :
610-10=600
600:5=120 (a)
120x4+10=490 (b)
