Answer 1

Explicație pas cu pas:

kg=176

m-mere

p-pere

c-caise

p+18=m

m+20=c

daca m+p+c=176kg atunci

p+18+p+p+18+20=176

3p+56=176

3p=120

p=40

m=58

c=78

Answer 2

m=p+18

c=m+20

p+18+p+m+20=176

p+18+p+p+18+20=176

3p+56=176

3p=176-56

3p=120

p=40 kg

m=40+18

m=58 kg

c=58+20

c=78 kg
