⠀

Two years ago, the father was 13 times as old as his son.

⠀

Therefore,

⠀

\begin{gathered}:\implies\sf 13(x - 2) = 7x - 2 \\\\\\:\implies\sf 13x - 26 = 7x - 2 \\\\\\:\implies\sf 13x - 7x = 26 - 2\\\\\\:\implies\sf 6x = 24 \\\\\\:\implies\sf x = \cancel\dfrac{24}{6}\\\\\\:\implies \underline{\boxed{\textsf{\textbf{x = 4}}}}\;\bigstar\end{gathered}

:⟹13(x−2)=7x−2

:⟹13x−26=7x−2

:⟹13x−7x=26−2

:⟹6x=24

:⟹x=

6

24

:⟹

x = 4
