Then two sisters are twins and they are 2 years younger than Lana.
anonymous
  • anonymous
We know Lana is \(2n\), so the two sisters are both \(2n-2\).
anonymous
  • anonymous
Set up the equation. Lana+ twin +twin+youngest =45
anonymous
  • anonymous
so what age is the youngest?
anonymous
  • anonymous
The youngest is n. I put that first. Read it.
anonymous
  • anonymous
so what is n?
anonymous
  • anonymous
\[2n+2n-2+2n-2+n=45\]Now solve for n.

I don't give out answers. YOU work for it.
anonymous
  • anonymous
so is it 7n-4?
anonymous
  • anonymous
Yes, but you need to find for n, right?
anonymous
  • anonymous
so 7n-4=5
anonymous
  • anonymous
\[\huge 7n-4=45\]

Add 4 on both sides. Then divide 7 on both sides.
anonymous
  • anonymous
so it is 7?
anonymous
  • anonymous
yes
