.
Let x be the number of the jeans sold of the brand A.

Then the number of those of the brand B is (32-x).


Your "money" equation is 

30x + 35*(32-x) = 1050.


Simplify and solve for x.


30x + 1120 - 35x = 1050

-5x = 1050 - 1120 = -70  ====>  x = %28-70%29%2F%28-5%29 = 14.



Answer.  14 jeans of the brand A and the rest 32-14 = 18 jeans of the brand B.


Check.  14*30 + 18*35 = 1050.   ! Correct !
