Suma a 5 numere consecutive este 170. Aflati numerele.

Answer 1

x + (x +1) +( x +2)  +(x +3)   +(x +4 ) = 170 
5x + 10 =170 
5x =170 - 10 
5x = 160 
x = 160 :5 = 32
numerele : 32 ;33;34;35 si  36

Answer 2

$a+b+c+d+e=170 \\ a+a+1+a+2+a+3+a+4=170 \\ 5a+10=170 \\ 5a=160 \\ a=32 \\ b=a+1=32+1=33 \\ c=a+2=32+2=34 \\ d=a+3=32+3=35 \\ e=a+4=32+4=36$
