Let F be the the first number. Let S be the second number that you would times by 5 to equal the first number. So far, you've got the equation .

They said that the sum of the two numbers, F and S is 270. That's .

We're going to do a substitution here. Since F = 5S, let's replace the F with a 5S in the equation .

<---- substitution done. This way, you'll only be solving for one variable with this single equation.

<----- Combined like terms.

<----- The smaller number turned out to be 35. If the first number is five times the second number, then the first number would be 35 * 5, or 175.
