Hello, princessice!
. .\(\displaystyle \boxed{\begin{array}{c}\text{Emily now} \\ 13 \end{array}} \quad\;\Rightarrow\quad\; \boxed{\begin{array}{c} \text{Emily in 5 years} \\ 18 \end{array}} \)

\(\displaystyle \boxed{\begin{array}{c}\text{Grandma now} \\ ? \end{array}} \quad\Leftarrow\quad
\boxed{\begin{array}{c} \text{Grandma 5 years} \\ 4\times18\,=\,72 \end{array}}\)
