Question

_+_-_=11 by using (2,4,6,8,10,12,14)

Answer 1

Given :

(2,4,6,8,10,12,14)

To find : _+_-_= 11

Solution :

Following are the steps we used in this

We used 10 in the first fill in the blank.In the second fill in the black we divided 14 by 2 and in the third fill in the blank we used 6 .

LHS

$10+( \frac{14}{2} )-\ 6\\= \ 10+7-\ 6\\= \ 17-\ 6\\=11$

that is equal to RHS Hence proved

Answer 2

Given:

2,4,6,8,10,12,14.

To find:

with the help of the above number find:

_+_-_=11

Solution:

In the given proving section there are only two operators is used. if we use the above-given number to prove the equation. It can't be possible, which can be defined as follows:

⇒ 6+4 -2 =8

⇒ 8+6-4= 10

⇒ 14+2-6 =10

that's why it can't be possible.
