Question 430525: Three times the larger of two numbers is equal to four times the smaller. The sum of the numbers is 21. Find the numbers. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let X and Y be our numbers. Then:
3X=4Y and X+Y=21.
3X+3Y=63
We substitute for 3X:
4Y+3Y=63
7Y=63
Y=9
X=21-Y=21-9=12.
