Question

I subtracted 11 from twice a number and the result was 15. Find the number.​

Answer 1

As per the data given in the question,

We have to determine the value of the number.

As per question,

It is given that,

If  11 is subtracted from twice a number and the result is 15.

So, let the number be = x

So, from the above,

Twice the number will be $=(2\times x) = 2x$

So, when 11 is subtracted from twice the number,

Then the value of number will be $=(2x-11)$

So, considering the overall statement,

We will get it as,

$(2x-11) = 15\\=>2x = 15+11\\=>2x = 26\\=>x = \frac{26}{2} = 13$

Hence, value of the number will be 13.

Answer 2

Answer:

The number is 13.

Step-by-step explanation:

To find-

determine the value of the number.

Solution -

given that -  11 is subtracted from twice a number and the result is 15.

let, the number be = x

We can write it as

= $(2$ × $x )$

= $2x$

When 11 is subtracted from twice the number,

Then the value of number will be = $2x - 11$

When 11 is subtracted from twice the number the result is 15

$2x - 11 = 15\\2x = 15 +11\\2x = 26\\x= \frac{26}{2} \\x = 13$

So, The number is 13
