Question

in trei saci sunt 140 kg . in primii doi sunt 95 kg , iar in ulimii doi 85 de kg . cate kg are fiecare sac ? dau fundita. e foarte urgentttt

Answer 1

a+b+c=140
a+b=95
b+c=85

a+85=140
a=140-85
a=55

a+b=95
b=95-55
b=40

b+c=85
c=85-40
c=45

Answer 2

a+b+c=140kg
a+b=95kg
b+c=85kg

c=(a+b+c)-(a+b)
c=140kg-95kg
c=45kg(in al treilea sac)

a=(a+b+c)-(b+c)
a=140kg-85kg
a=55kg(in primul sac)

b=(a+b+c)-(a+c)
b=140kg-(55kg+45kg)
b=140kg-100kg
b=40kg(in al doilea sac)
