Investment Distribution Problem

Samantha has some savings that she plans to invest in a fund. The amount she invests in Fund X is twice the amount she invests in Fund Y. If she invests $900 in total across both funds, what is the amount she invests in Fund Y?

Let the amount invested in Fund Y be denoted by $y$. Then, the amount in Fund X can be expressed as $2y$. Therefore, we can set up the equation:

$y + 2y = 900$

Using this information, determine the amount invested in Fund Y.
