Question

if a number is doubled and the result is increased by 8 we get 40 what is the number

Answer 1

The number is 16

Given : A number is doubled and the result is increased by 8 we get 40

To find : The number.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to determine the number)

Let, the number = x

By doubling the number, we get :

= x × 2

= 2x

Increasing the double of the number by 8, we get :

= 2x + 8

According to the data mentioned in the question,

2x + 8 = 40

2x = 40-8

2x = 32

x = 32/2

x = 16

The number is = x = 16

(This will be considered as the final result.)

Hence, the number is 16

Answer 2

Answer:

16

Step-by-step explanation:

Let the number be x

the number is doubled = 2*x = 2x

result increased by 8 = 2x + 8

we get 40

equation form is :  2x + 8 = 40

                              2x = 40 - 8

                              2x = 32

                               x = 32 / 2

                               x = 16
