You can derive both 1st and 3rd law from the 2nd law.

Explanation:

1st law states that an object at rest will remain at rest or an object moving with a uniform velocity will continue to do so unless acted upon by an external force.

Now, mathematically 2nd law states #F=ma#.
If you put #F=0# then automatically #a=0# because m=0 has no meaning in classical mechanics.
So veloctiy will remain constant (which also includes zero).
