Answer:
Step-by-step explanation:
y/4 - 4 = 3
Add four to both sides | y/4=7
We know that 7*4=28 so therefore y must be 28 | 28/4=7
7=7
Therefore y=7
If one cant be given, then most likely 12. Using 3 as the integer, as they would be the second lowest number.. and multiplying it by 4, 12.
There are 4 seats in total.
There are 4 ways to fill 1st seat.
When 1st seat is filled, there will be 3 ways to fill the second seat.
Similarly there will be 2 ways to fill the third seat and 1 way to fill the last seat.
So, total number of ways the seats can be filled = 4 x 3 x 2 x 1 = 24 ways.
Therefore, the correct answer is option A
Y=x-4
x=y+4
y=-3(y+4)
y=-3y-12
4y=-12
y=-3
x=1
