Question

PLEASE HELP!!! WILL REWARD!!

Answer 1

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

Answer 2

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<span />
