This problem is one of classic entertainment problem, and it is classic problem to acquaint beginning students
with systems of equations.
Unfortunately, in your post the problem is posed INCORRECTLY,
showing absolute absence of knowledge on the subject.
As it is worded in the post, many different answers are possible,
which makes the educational value of the posed problem equal to zero, if not negative.
The correct formulation of the problems should bring, in addition, info about the total number of insects in the box.
For this type of problems, see the lessons
- Problem on two-wheel and three-wheel bicycles
- Problem on animals at a farm
- Problem on pills in containers

in this site.
Learn the subject from good sources (!)
Also, the words " . . . a box which consists of 270 legs . . . " sound BAD in English: they make inappropriate combination.
Much better is to say "there are 270 legs in the box, in all".
Learn English parallel with Math (!)
Happy learning (!)
