Answer:
The two numbers are 8 and 4
Step-by-step explanation:
x is one number
y is the other number
x+y = 12
x - y = 4
Add the two equations together
x+y = 12
x - y = 4
-----------------
2x = 16
Divide by 2
2x/2 = 16/2
x = 8
Now find y
x+y = 12
8+y = 12
y = 12-8
y = 4
The two numbers are 8 and 4
24 : 15
divide both by 3
8 : 5
I think the answer is the second one b
