4. Elena noticed that, nine years ago, her cousin Katie was twice as old as Elena was then,
Then Elena said, “In four years, I'll be as old as Katie is now!" If Elena is currently e years
old and Katie is k years old, which system of equations matches the story?

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

1/4 is the asnwer cuz 5/20 is the faction
