Answer 1

Given:

Twice a certain number plus 6 gives a result of 28

To find:

How can this statement be written?

Solution:

The given statement is : ''Twice a certain number plus 6 gives a result of 28''

Let the number is N

Twice a number means, we need to multiply the number by itself.

=> N x N = 2N

So, twice a number = 2N

Now, According to the given question:

Twice a certain number plus 6 gives a result of 28

=> 2N + 6 = 28

Hence, the required mathematical equation is 2N + 6 = 28.

Extra Knowledge:

Finding that number:

2N + 6 = 28

=> 2N = 28 - 6

=> 2N =22

=> N = 22/2

=> N = 11.
