Answer:

x = 5.5

y = - 6.5

Explanation:

Let one of the numbers = x

Let the other number = y

x + y = - 1

x = y + 12 Put the second equation into the first one

y + 12 + y = - 1 Subtract 12 from both sides

y + y = - 1 - 12 Combine both left and right sides

2y = - 13 Divide by 2

2y/2 = - 13/1

y = - 6.5

x + y = - 1

x - 6.5 = - 1 Add 6.5 to both sides

x = 5.5
