Question

Just to keep minds working...
Financial dealings. The little tycoon Johnny says to his fellow capitalist Annie, “If I add 7 dollars to 3/5 of my funds, I’ll have as much capital as you do.” To which Annie replies, “So you have only 3 dollars more than me.” How much money do they have?

Answer 1

Lets say Johnny and Annie have x and y dollars respectively, we can come up with this system:
\[7+\frac{3}{5}x=y\]
\[x-3=y\]

Answer 2
