The sum of two numbers is 3 , Their difference is -12 . Find the numbers

Answer 1

Hi Washington, the best way to approach this is to look at the info they provided.

If one number = X and the other = Y, you know that ...

X + Y = 3

and

X - Y = -12

Turn the first math sentence into X= 3 - Y and sub into the second math sentence to solve!
