Question

The product of two integers is -21. The difference between the integers is -10. The sum of the two integers is 4. What are the two integers?

Answer 1

The product of 2 integers = -21

Let one integer be x and the other will be -21/x

Difference = -10 , so x - (-21/x) = -10

Sum = 4 , so x + (-21/x) = 4

Find x using these quations...

Answer 2

{x y = -21, x - y = -10, x + y = 4}
{x = -3, y = 7}
