So first your going to multiply 2 times 3x= 6x
and multiply 2 by -3y= -6y
so now the equation is 4x+8y+6x-6y
then combine like terms
4x+6x
and 8y-6y
equals 10x+2y

Answer:
Lori will have
cavity if she brushed for
each night.
Step-by-step explanation:
As the question suggests cavities developed varies inversely with the number of seconds spent on brushing.
Lets take the terms as
,where
is the constant of proportionality.
And
c = Number of cavities developed each year
t = Number of minutes spent on brushing per night
Now we will plugging the values of the given terms and find the value of
,for this we can re-arrange it as...
and 

Now as Lori will increase her brushing time so as the cavity will decrease.
So for this we have been given,
and
.
As 
So as per Paul's observation if Lori brushed for
at night she will have
cavity on that year.
