The sum of two numbers is 14. When one number is added to twice the other number, the result is 25. Find the numbers
ELEN [110]

Let x and y be the two numbers. We have:

\begin{cases}x+y=14\\x+2y=25\end{cases}

Subtract the first equation from the second to get

y=11

And deduce

x+11=14 \iff x=3

The two numbers are 3 and 11.
