1. Step-by-step explanation:

   Let the number to be x

   According to the condition,

   [tex]3x-5=16[/tex]

   [tex]⇒3x=16+5[/tex]

   ⇒

   [tex]3x=21[/tex]

   ⇒

   [tex]x=\frac{21}{3}[/tex]

   ⇒

   [tex]x=7 [/tex]

   ∴The required number is 7.

2. Given : 5 subtracted from 3 times a number,the number result is 16.

   To Find : The Number.

   [tex]{\underline{\boldsymbol{\pink{According \ to \ the \ question \ :}}}}[/tex]

   Given that,

   5 subtracted from 3 times x. i.e. 3x – 5

   [tex]\\[/tex]

   [tex] : \implies{ \sf{3x – 5 = 16}} [/tex]

   [tex]\\[/tex]

   Adding 5 to both sides,We get

   [tex] : \implies{ \sf{\pink{3x-5+5=16+5}}}[/tex]

   [tex] : \implies{ \sf{\pink{3x=21}}} [/tex]

   [tex]\\[/tex]

   Dividing both sides by 3,We get

   [tex] : \implies{ \sf{\pink{3x/3=21/3}}} [/tex]

   [tex] : \implies{ \sf{\pink{x=7}}} [/tex]

   [tex]\\[/tex]
