Answer:

-950

Step-by-step explanation:

Arithmetic sequence=a+(n-1)d

a=first number

n=nth term

d=difference

a=25

n=66

d=-15

So let's solve

25+(66-1)(-15)

25+(65)(-15)

25-975

-950

So the 66th terms is -950

So the equation is 2x + y = 9
you want to solve the equation so that y is on one side. in order to do this you need to subtract 2x from BOTH sides to get y by itself.
after, you should get y = 9 - 2x
