Answer 1

$\large\underline \bold{QuesTion - }$

$\star$ If x- 9 = 16, then find the value of 3x-75 .

$\large\underline \bold{GivEn - }$

$\red{\sf \: x - 9 = 16}$

$\blue \implies \red{\sf \: x = 16 + 9}$

$\blue \implies \red{\sf \green{\underline{\boxed{ \rm x = 25}}}}$

$\large\underline \bold{SolutiOn - }$

Put the value of X in given equation ,

we found x = 25 ,

Therefore,

$\pink{ \rm \therefore \: 3x - 25 = 3(25) - 25}$

$\pink{ \rm \therefore \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 75 - 25}$

$\pink{ \rm \therefore \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 50}$

Hence , The value of (3x-25) is 50.

Answer 2

Answer:

=> The value of $3x-75$ is 0.

Explanation:

Given that:-

$x- 9 = 16$

To find:- The value of $3x-75$,

First of all, we have to find the value of x,

As we have,

=> $x- 9 = 16$

Now add both sides by $9$, we get

=> $x- 9 +9= 16+9$

Simplifying it further,

=> $x = 25$

Now put the value of x in $3x-75$,

=> 3 ( 25 ) - 75

=> 75 - 75

=> 0

Hence, the required solution is 0.
