(a^{m})^{n}=a^{m*n}\\\\\frac{1}{a^{-m}}=a^{m}

4. Elena noticed that, nine years ago, her cousin Katie was twice as old as Elena was then,
kakasveta [241]

Answer:

k - 2e + 9 = 0

k - e - 4 = 0

Step-by-step explanation:

Given that Elena is currently e years  old and Katie is k years old. Now, nine years ago, Katie was twice as old as Elena was.

So, k - 9 = 2(e - 9)

⇒ k - 2e + 9 = 0 .............. (1)

And, in four years, Elena will be as old as Katie is now.

So, k = e + 4

⇒ k - e - 4 = 0 ............... (2)

Therefore, the equations (1) and (2) matches the conditions. (Answer)
