The sum of two numbers is −48 and their difference is 17. Find the numbers.
pls asap

a = -15.5, b = -32.5

Step-by-step explanation:

Let's say the first number is a, and the second is b.

a + b = - 48

a - b = 17

If you add both equations, you get 2a = -31, because the

+b and -b cancel each other.

So you would get a + a = 2a, then -48 + 17 = -31

2a = -31

---      ---

2         2

Divide both sides by 2 to get a by itself.

a = -15.5

Then let's go to the next equation (a - b = 17)

Plug in a..

-15.5 - b = 17

+ 15.5       + 15.5

-b = 32.5

---    

-1       -1

b = -32.5

Hope this helps.
