Answer 1

X: 6 r 5=>x=6•C/1 + 5 => x-5 =6•C1+5} X: 7 r5 =>x=7•C/2+5=>x-5 = 7•c2+5}=>x€[6,7,8] X: 8 r5 =>x=8•C/3+ 5=>x-5= 8•C3+5} [6,7,8] =2 la a 3a • 3• 7= 168 6 = 2•3 7 = 7 8 = 2la a 3a X-5 = 168 X= 168-5 X= calculezi tu.

Answer 2

Vom nota cu n numarul necunoscut.
$n:6= c_{1} ,rest 5$====>$n=6 c_{1} +5$=>$n-5=6 c_{1}$
$n:7= c_{2} ,rest 5$====>$n=7 c_{2} +5$=>$n-5=7 c_{2}$
$n:8= c_{3},rest 5$====>$n=8 c_{3}+5$=>$n-5=8 c_{3}$

===>$n-5=[6,7,8]$
$6= 2^{1} * 3^{1}$
$7=                              7^{1}$
$8= 2^{3}$
________________________________
$[,]= 2^{3} *3*7=8*3*7=56*3=168$

    In urna de votare sunt 168 de buletine.
