Answer:
x = 37 y = 12
Step-by-step explanation:
Let x be one number
Let y = other number
x+y = 49
x-y = 25
Add the equations together
---------------
2x = 74
Divide by 2
2x/2 = 74/2
x =37
37+y = 49
Subtract 37 from each side
37+y-37 = 49-37
y = 12
15.1
The answer is B or -3.132
You are multiplying 2 negatives and a positive, so it guarantees it will be negative! Hope this helps!
