$\Huge{\sf{\fcolorbox{pink}{white}{Solution }}}$

Here,we have to find the value of x by linear equation method and after finding the value then we have to check it by putting the value which we find.

$\: \: \: \: \: :\sf \implies \: 3(x - 3) = 15 \\ \\ \\ \: \: \: \: \: \: \: \: \: \: \: : \sf \implies \: 3x - 9 = 15 \\ \\ \\ \: \: \: \: \: \: \: \ \: \: \: \: \: \: : \sf \implies \: 3x = 15 + 9 \\ \\ \\ \: \: \: \: \: \: \: \: : \sf \implies \: 3x = 24 \\ \\ \\ \: \: \: \: \: \: \: \:$

$\sf{\dag{\underline{\fbox{x = 8}}}}$

Now,check it

$\: \: \: : \sf \implies3(x - 3) = 15 \\ \\ \: \: \: \: \: : \sf \implies \: 3(8 - 3) = 15 \\ \\ \: \: \: \: : \sf \implies24 - 9 = 15 \\ \\ \: \: \: \: \: : \sf \implies \: 15 = 15$

Hence,it is proved
