    Ta có:
    |x+1|+|x+2|+|x+3|+|x+4|+|x+5|=16
    -> x+1+x+2+x+3+x+4+x+5=16
    -> (x+x+x+x+x)+(1+2+3+4+5)=16               
    -> 5+x+15=16
    -> 5+x=16-15
    -> 5+x=11
    -> x=11+5
    -> x=16
          Vậy x=16

    x+1+x+2+x+3+x+4+x+5=16
    (x+x+x+x+x)+(1+2+3+4+5)=16               
    5+x+15=16
    5+x=16-15
    5+x=11
    x=11+5
    x=16
