Answer 1

Răspuns:

a=576 ; b=714 ; c=1332

Explicație pas cu pas:

$a+b+c=2622$

$a/2-54=2x=>a/2=2x+54=>a=4x+108$

$b/2-123=2x+2=>b/2=2x+123=>b=4x+246$

$c/2-432=2x+4=>c/2=2x+432=>c=4x+864$

$4x+108+4x+246+4x+864=2622 =>12x+1218=2622=>12x=1404=>x=1404/12=>x=117$

$a=4*117+108=>a=468+108=>a=576$

$b=4*117+246=>b=468+246=>b=714$

$c=4*117+864=>468+864=>c=1332$

$Raspunsul$ $corect:$ $a=576,b=714,c=1332$
