Answer 2

Question :

⠀⠀ ⠀▪︎⠀Think of a number . Add 11 to it and devide the sum by 7 , the result is 9 . What was the number ?

$\rule{100}{1.5}$

Given : The number when it is added to 11 and devided by 7 , the result is 9 .

Need To Find : The number ?

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀

❍ Let's say that , the number be x .

$\\\qquad \:\:\bigstar \:\:\underline {\pmb{\pink {\sf \: According \:To\:The \:Question \:\::\:}}}\:$

⠀⠀⠀▪︎⠀If , the number when it is added to 11 and devided by 7 , the result is 9 .

$\\:\implies \sf \bigg\{ \dfrac{ Number + 11 }{7}\bigg\}=\:9\:$

$:\implies \sf \bigg\{ \dfrac{ x + 11 }{7}\bigg\}=\:9\:$

$:\implies \sf \dfrac{ x + 11 }{7} \:=\:9\:$

$:\implies \sf x + 11 \:=\:9\:\times \:7\:$

$:\implies \sf x + 11 \:=\:63\:$

$:\implies \sf x \:=\:63\:- \:11\:$

$:\implies \pmb {\underline {\boxed {\purple {\:\frak{ \:x\:\:=\:52\:}}}}}\:\bigstar \:$

Therefore,

• The number is , x = 52

$\qquad \therefore \:\underline {\sf Hence, \:The \:Number \:is \: \pmb{\sf 52\:}\:.}$
