If you want to find out their ages in the past, then you subtract x years from their current age.

So x years ago, Kaylene was years old. Since Kaylene was twice as old as Jessica, this means if you multiply Jessicas age x years ago by 2 you'll get Kaylene's age. In other words, Jessica was years old

Set up the translated equation

Subtract 30 from both sides

Add 2x to both sides

Combine like terms on the left side

Combine like terms on the right side
