Question

determine two integers whose sum is 4 and i difference is 4
fast please​

Answer 1

Answer:

There is not “the” pair of integers whose difference is -4, as there are infinite pairs of integers that satisfy that condition.

You can do this easily, following these steps:

Pick any integer, yes, even 1 billion.

Add 4 to it to get a new number, use a calculator if needed. If you did it correctly, this number will still be an integer.

Subtract this new number from the first one (please don't ask for the answer on Quora though).

Wow! Congratulations, you found a pair of numbers whose difference is -4.

Repeat for all numbers.

You may think I am a wizard, but this is just an old trick that my old man taught me.

Answer 2

Answer:

Another way

a+b=4

a-b=4

add them

2a=8

a=4

4+b=4

b=0
