Given :

• A number which when multiplied by 8 and then reduced by 9 is equal to 47.

To find :

• The number ?

Solution :

Let

• the required number be x

According to question,

• A number which when multiplied by 8 and then reduced by 9 is equal to 47 { Given }

$\sf → 8 ×x-7=47\\ \tt→ 8x-9=47</p><p>\\ \sf→ 8x=47+9</p><p>\\ \tt→ 8x=56</p><p>\\ \sf→ x=56/8</p><p>\\ \tt→ x=7$

Question [¡¡]

The sum of two numbers is 72. If one of the number is 6 more than the other, find the numbers.

let ,

• one number be x

and

• the another number be y

so,

According To The Question,

• → x + y = 72 _____(¡)

also,

given that,

one of the number is 6 more than the other

so,

→ x = y + 6_____(¡¡)

• putting the value of x in (¡)

$\tt→ x + y = 72</p><p></p><p>\\ \sf→ y + 6 + y = 72</p><p></p><p>\\ \tt→ 2y = 72 - 6</p><p></p><p>\\ \sf→ 2y = 66</p><p></p><p>\\ \tt→ y = 66/2</p><p></p><p>\\ \sf→ y = 33$

now,

• putting the value of y on (¡¡)

$\\ \tt→ x = y + 6</p><p></p><p>\\ \sf→ x = 33 + 6</p><p></p><p>\\ \tt→ x = 39$

Hence,

• the required numbers are 39 and 33
