Respuesta :
x+y+z=t
simple..
there are no other numbers that we have to follow like (1/2x or 3/4y) so it is just all together=t. the x, y, z will equal t because t is the total number of students taking three languages. And that number should be equivalent to x,y,z combined.
otherwise?? i d k

Answer:
x+y+z-2t
Step-by-step explanation:
There are t students taking all three and the rest take only 1 language.
The number taking only Oriya is x-t .
The number taking only Dakhini is y-t .
The number taking only Dutch is z-t .
So the number of students altogether is
x-t + y-t + z-t + t = x+y+z-2t.
Hope this helps! :D
