Answer 1

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

To Find : The Number.

⠀⠀⠀⠀_____________________

❍Let the required number be x.

${\underline{\boldsymbol{\pink{According \ to \ the \ question \ :}}}}$

Given that,

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

$: \implies{ \sf{3x - 5 = 16}}$

Adding 5 to both sides,We get

$: \implies{ \sf{\pink{3x-5+5=16+5}}}$

$: \implies{ \sf{\pink{3x=21}}}$

Dividing both sides by 3,We get

$: \implies{ \sf{\pink{3x/3=21/3}}}$

$: \implies{ \sf{\pink{x=7}}}$

${ \underline{ \textsf{Thus, \: The \: required \: number \: is {\textbf{x = 7}}}}}.$

Answer 2

Step-by-step explanation:

Let the number to be x

According to the condition,

$3x-5=16$

$⇒3x=16+5$

⇒

$3x=21$

⇒

$x=\frac{21}{3}$

⇒

$x=7$

∴The required number is 7.
