Answer 2

Answer:

Hey buddy, here's your answer

Step-by-step explanation:

The sum of two numbers is 12 or: X+Y= 12

Ine number is three times the other or: X=3Y

Now replace the value of X from the second equation into the first equation: 3Y+Y=12

Now solve the equation to get the value of Y:

4Y=12 and Y=12/4 then Y=3

Now if Y=3 and X=3Y then solve the equation for the value of X:

if X=3Y then X=3x3 so X=9

The two numbers are 3 and 9
