Jack's age is \(y\) and Jill's age is \(x\). "Jack's age next year will be twice Jill's age last year" How do we write this using our variables?

  • anonymous
Here is a hint: "Jack's age next year" \(y+1\) "Jill's age last year" \(x-1\) So: "\(y+1\) will be twice \(x-1\)"

You need to start turning this into an equation first.

Good. Now how do you write: "Their present ages total 45."

Hint: total means we need to do addition.

y-1=2(x-1)+45

Nope, this is a separate equation. We don't need to worry about the first equation right now.

"Their present ages total 45." Is a separate equation. Hint: it will have \(y+x\) in it.
