Ava used the following equation in order to solve a math problem involving integers.

-h/-k = j

if the equation ava used is correct, which of the following equations is not correct?

a) - j = -h/k
b) - j = -h/-k
c) - j = h/-k
d) j = h/k

The only equation which is incorrect is in option B.

Step-by-step explanation:

Eva used the following equation in order to solving integers, which is  

⇒ ......... (1)

Now, if the equation Ava used is correct, then we have to find which of the given equations is not correct.

Now, in option A) it is given that

⇒ which is same as equation (1).

In option B) it is given that

⇒ which is not same as equation (1).

In option C) it is given that

⇒ which is same as equation (1).

Again, in option D) it is given that

⇒ which is same as equation (1).

Therefore, the only equation which is incorrect is in option B. (Answer)
