Question

If 12 is subtracted from twice a number, the result is 24. Find the number​

Answer 1

Solution :-

• Let the number be "x"
• If 12 is subtracted from twice the number, the result is 24
• Twice of x is 2x

⇒ 2x - 12 = 24

⇒ 2x = 24 + 12

⇒ 2x = 36

⇒  x = 36/2

⇒ x = 18

∴The number is 18

Answer 2

Answer:

The required number is $18$.

Step-by-step explanation:

Given : If $12$ is subtracted from twice a number, the result is $24$.

To find : The number = ?

Solution :

• It is given that "If $12$ is subtracted from twice a number, the result is $24$."
• We have to find the number.
• Let, $x$ be the number.
• According to given condition, the equation becomes

      $2x-12=24$

• Transpose $12$ at other side, we get

          ∴ $2x=24+12$

           ∴ $2x=36$

           ∴ $x=\frac{36}{2}$

           ∴ $x=18$

• ∴ The required number is $18$.
