N=(3/4)*h*d
--------------------
n=Number of hours she reads
h=Hour(s)
d=Days
--------------------
You see, with this formula - when d=2,
n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours
So, in the space of 2 days, she had spent 1.5 hours reading.
I think it’s 24 I could be wrong but I’m pretty sure
Subtract the y then add the 4 to the other side so y=0
5x = 15
x = 3
3(3) - 5y = -16
9 - 5y = -16
5y = -16 - 9
5y = - 25
y = - 5
(3, -5)
