25 students
hope this helps
So here. I don't know how to explain so-
Answer:
3n + 75
Step-by-step explanation:
Multiply n by 3 = 3n
Multiply 25 by 3 = 75
If (-5) = x then the anwser should be
-234
There is no solution for the first one
if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15
- there is no solution to theses
a23 means the element in the second row and the 3rd column
so its -5
