So it follows from the theorem that:
[tex] \sf{6(6 + x) = 5(5 + x + 3)}[/tex]
Solve the resulting equation for x:
[tex] \sf \longrightarrow{36 + 6x = 25 + 5x + 15}[/tex]
[tex] \sf \longrightarrow{6x - 52 = 25 + 15 – 36}[/tex]
[tex] \sf \longrightarrow{x = 4}[/tex]
[tex]\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}[/tex]
[tex] \bm{The \: \: value \: \: of \: \: x \: is \: \: 4}[/tex]
