Homework Help: Algebra

Word problem:

The sum of two numbers is 26.4. One number is five times the other number. Find the numbers.

It's probably:
x+y=26.4
x=5y

But, I could be wrong and I don't know where to go from there.

5y + y = 26.4

6y = 26.4

y = 26.4/6

y = 4.4

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Let's see if that's right.

4.4 + (5*4.4) = 26.4

4.4 + 22 = 26.4

Right!
