Question 489560: The sum of two numbers is 15. Three times one of the numbers is 11 less than five times the other.Find the numbers Answer by unlockmath(1688) (Show Source):
You can put this solution on YOUR website! Hello,
Let's have x and y be the two numbers. We can make 2 equations:
x+y=15 or x=15-y
3x=5y-11
Use substitution:
3(15-y)=5y-11
Distribute and get y alone:
45-3y=5y-11
56=8y
y=7
x=8
There we go.
Make sense?
