Question

The difference of an integer x and -7is 18 find the value of x

Answer 1

Answer:

the value of x is 11

Step-by-step explanation:

x-(-7)=18 (((-×-=+)))

x+7=18

x=18-7

x=11

Answer 2

Answer:

x = 11 , -25

Solution:

Here,

We need to find the integer x , such that the difference of x and -7 is 18 .

Thus,

=> | x - (-7) | = 18

=> | x + 7 | = 18

=> x + 7 = ± 18

Here,

Two cases arises.

Case(1) :

=> x + 7 = 18

=> x = 18 - 7

=> x = 11

Case(2) :

=> x + 7 = - 18

=> x = - 18 - 7

=> x = - 25

Hence,

The required values of x are 11 and (-25).

Verification :

Case(1) : If x = 11

Difference of x and - 7 = 11 - (-7)

= 11 + 7

= 18

Case(1) : If x = -25

Difference of x and - 7 = -7 - (-25)

= -7 + 25

= 18

Hence verified.

Note:

Difference = Larger no. – Smaller no.
