Question

The sum of two numbers is -16 and their difference is 8. find the numbers.

Answer 1

The two numbers are -4 and -12

Explanation:

For this, we can use a little bit of algebra. Let x and y be the two numbers. We know that

x + y = -16

and

x - y = 8

Now, by adding the two equations together, we get

(x + y) + (x - y) = (-16) + 8 = 8

2 x = -8

x = -4

Since we know x = 4 now, we can substitute it into the first equation

x + y = -16

(-4) + y = -16

y = (-16) - (-4) = (-16) + 4

y = -12

The two numbers you are looking for are -4 and -12
