Answer:

One number is 3 times another number. If 15 is added to both the numbers, then one of the new numbers becomes twice that of the other new number.

Answer 2

Answer:

-5/2,-15/2

Step-by-step explanation:

x+y= -10

x-y= 5 --> x=y+5

x+y = -10

y+5+y = -10

2y = -15

y = -15/2

x = -15/2 + 5 = -5/2
