Question

Poblema 12 va implor din suflet

Answer 1

 [a+(a+8)+(a+16)]3=27
(3a+24)/3=27
3a+24=27*3
3a+24=81
3a=81=57
a=57/3 =19= primul numar
a+8=19+8= 27 al doilea numar
a+16= 19+16= 35 al treilea numar

Answer 2

b=a+8
b=c-8 =>c=b+8
(a+b+c) :3=27
(a+a+8+a+8+8):3=27
(3a+24):3=27
3a+24=27×3
3a+24=81
3a=81-24
3a=57
a=57:3
a=19
b=19+8=27
c=27+8=35
