[tex]\underline{\mathbb{SOLUTION:}}[/tex]

- Represent x and y as the ages of her sister and Kimberly respectively. Formulated equations of the given statement.

  • [tex]\begin{cases}x=36&\red{(eq. \:1)}\\x=2y-14&\red{(eq. \: 2)} \end{cases}[/tex]

- Substitute x from the first equation to the second equation in terms of y which is the age of Kimberly.

  • [tex]\begin{cases}x=36\\36 = 2y - 14\end{cases}[/tex]

  • [tex]\begin{cases}x=36\\36 + 14 = 2y\end{cases}[/tex]

  • [tex]\begin{cases}x=36\\50 = 2y\end{cases}[/tex]

  • [tex]\begin{cases}x=36 \\ \begin{gathered} \frac{50}{2} = \frac{ \cancel2y}{ \cancel2} \end{gathered}\end{cases}[/tex]

  • [tex]\begin{cases}x=36\\y = 25\end{cases}[/tex]

[tex]\therefore[/tex] Kimberly is 25 years old.
