Quote:

The sum of two numbers is 85. Twice one number plus four times the other is 218. Determine the numbers.

x + y = 85
2x + 4y = 218

y = 85-x

2x + 4(85-x) = 218
-2x + 340 = 218
-2x = -122
x = 61
y = 85 - x = 85 - 61 = 24

Nobody Special:

In an arithmetic sequence a_8 = 9 and a_12 = 37. What is a_13?
Is there an equation or something that I'm missing here? Something to simplify it?

If anyone has any ideas, that would be awesome! ^_^

CPhill:

No variable remains after we simplify the left side.

We get

- 1 = - 7

An impossibility!!!

babyy:

m=-1
but how can i get that number?
f(x)=(m+3)x+m-2
f(-2)=-7
