Answer 1

Răspuns:

357:a=21

a=357:21=>a=17

1536:(b+20)=64

b+20=1536:64

b=24-20=>b=4

(176:4+8×7) :c =20

(44+56):c=20

100:c=20=>c=100:20=>c=5

__________________

a=712+1=>a=713

a:b=3 rest 2

713:b=3 rest2

713=3b+2

713-2=3b

b=711:3=>b=237

c=13b=>c=13·237=>c=3081

a+b+c=713+237+3081

a+b+c=4031
