This is how I would do it:
-8x=28-4y divide the entire equation by 4
-2x=7-y Put y back on the left and put x on the right
y=7-2x.
we are given

Firstly, we will factor numerators and denominators

we can see that
n^2 -6 is factor on both numerator and denominator
so, it will get cancelled
and n^2 -6 can not be equal to 0
so, one of restriction is


we can simplify it

we know that denominator can not be zero


so, option-B.......Answer
Answer:
-5
Step-by-step explanation:
i tried my best but this is the result
It would be (12,20) or (20,12) I don't know which one

40x=356000 x= 8900 applications
you make x the number of total applications
