Answer:
The weight of box and pocking material [tex]=13[/tex] pound
Step-by-step explanation:
Let the weight of box and packing material [tex]=x[/tex]
weight of package [tex]=192[/tex] pounds
total weight [tex]=205[/tex] pound
[tex]x+192=205[/tex]
Subtract both side by [tex]192[/tex]
[tex]x+192-192=205-192\\x+0=13\\x=13[/tex]
Hence weight of box and packing material [tex]=13[/tex] pound
