Question

A number such that its two- seventh is 12 *​

Answer 1

Answer:

42

Step-by-step explanation:

2/7*x=12

2x/7 =12

2x=12*7

x=12*7/2

x=6*7

x=42

Answer 2

Answer:

Let x be the number

Hence, seven times of the number =7x

Thirteen times of the number =13x

ACQ

7x=13x−12

⇒ 12=13x−7x

⇒ 6x=12

⇒ x= 6/12

⇒ x=2

Therefore, the required number is r−2.
