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.

  • Algebra - ,

    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!
