Question

5. If I subtract 8 from twice a certain number, the result is 19. What is the number?​

Answer 1

Answer:

Hence, the value of the number will be 13.5

Step-by-step explanation:

In context to questions asked

We have to determine the value of the number

As per questions

We have

If 8 is subtracted from twice a certain number then the resultant is 19

So, for determining the value of the number, let us assume that the number is x

So, twice of the number will be 2x

Now if 8 is subtracted from twice the number, then we will get the resultant as,

$2x - 8$

As the obtained number is equal to 19

So, after equating both

We will get,

$2x - 8 = 19 \\ = > 2x = 19 + 8 \\ = > 2x = 27 \\ = > x = \frac{27}{2} \\ x = 13.5$

Answer 2

Answer:

the number will be 13.5

Step-by-step explanation:

let the number be x

2x-8=19

2x=27

27/2 = 13.5
